Available in PDF, EPUB and Kindle. Book excerpt: With over 16 countries represented, this book represents international developments in the field of film synthesis and growth using energetic beams. It focuses on pulsed-laser deposition. Fundamental issues pertaining to the generation of laser ablation plumes, temperature distributions and collisional effects are described. Ion-assisted pulsed-laser deposition, pulsed-ion deposition, applications of hyperthermal beams and aspects of surface dynamics are discussed. The inclusion of an ion beam with the ablation process leads to some unique modifications in the thin-film growth mechanisms, and hence, film properties. Likewise, the collision of high-mass metal cluster ions with substrates shows promise for growth of novel structures. Also featured are new developments of optoelectronic materials, nitrides and carbon films using a variety of techniques. The effects of beam-induced defects on growth and surface morphology, chemical effects during growth, and characterization of film growth and film properties are addressed.

Available in PDF, EPUB and Kindle. Book excerpt: In the area of nucleation, it was discovered that C--0 thin films are perfect substitutes for diamond seeds in the growth of diamond films. This research, along with a careful study of diamond growth on carbon ion implanted single crystal copper, have clearly demonstrated that structured carbon is the best precursor for nucleation and growth of diamond films on non-diamond surfaces. In addition, by using fluorine chemistry during diamond growth, it has been shown that diamond films can grow on carbide substrates without the pretreatment of diamond seeding. The growth rates are higher and the film adhesion is much improved.
Download or read book Electron and Photon Beam Induced Thin Film Growth written by Ferenc Bozso and published by . This book was released on 1992 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: The small dimensions of novel electronic and optoelectronic device structures and their abruptly and unconventionally changing material compositions require high levels of spatial and kinetic control of the surface chemical reactions which are involved in the materials' growth or modification. These requirements exclude high temperature processes based on thermally activated chemical reactions. Directed energetic beams (electrons, photons, ions), however, can induce reactions at low temperatures, as well as provide for spatial and kinetic control in microfabrication processes. Electrons and photons of sufficient energy can cause fragmentation and desorption of adsorbed molecules or fragments of them, by inducing electronic excitations to dissociative states. The surface species after such excitations arc mostly of highly reactive radical character, which readily react with the substrate and with other radical or molecular species in the adsorbed layer. The formation of such reactive surface species in a controlled way can provides a basis for non-thermal selective area film growth.

Available in PDF, EPUB and Kindle. Book excerpt: Laser and Ion Beam Modification of Materials is a compilation of materials from the proceedings of the symposium U: Material Synthesis and Modification by Ion beams and Laser Beams. This collection discusses the founding of the KANSAI Science City in Japan, and the structures, equipment, and research projects of two institutions are discussed pertaining to eV-MeV ion beams. A description of ion beams as used in materials research and in manufacturing processes, along with trends in ion implantation technology in semiconductors, is discussed. Research into ion beams by China and its industrial uses in non-semiconductor area is noted. For industrial applications, developing technology in terms of high speed, large surface modifications and use of high doses is important. Thus, the development of different ion beam approaches is examined. Industrial applications of ion and laser processing are discussed as cluster beams are used in solid state physics and chemistry. Mention is made on a high power discharge pumped solid state physics (ArF) excimer laser as a potential light source for better material processing. Under ion beam material processing is nanofabrication using focused ion beams, important for research work in mesoscopic systems. Progress in the use of ion-beam mixing using kinetic energy of ion-beams to mingle with pre-deposited surface layers of substrate materials has shown promise. Advanced materials researchers and scientists, as well as academicians in the field of nuclear physics, will find this collection helpful.
Download or read book Advances in Superconductivity IV written by Hisao Hayakawa and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1086 pages. Available in PDF, EPUB and Kindle. Book excerpt: Five years have passed since the breakthrough in the critical temperature for superconductors. During this period, many superconducting materials have been discovered and developed, and our knowledge of the physical and other properties of oxide superconductors has deepened through extensive and intensive research. This knowledge has advanced superconductivity science and technology from the initial questioning stage to a more developed but still uncertain second stage where research activity in superconductivity now overlaps with fields of application. Generally speaking, science resonates with technology. Science not only complements but also competes with or stimulates technology. New scientific knowledge has triggered the second technological research stage. Much progress has been made in the development of practical devices, encouraging the application of superconductors in areas such as human levitation, a high speed levitated bearing, large current transforming leads, and high frequency devices. This technological progress has increased our understanding of the science involved, such as flux pinning and dynamics, and anomalous long-range superconducting interactions. At this important stage, international cooperation and collaborative projects can effectively sustain aggressive research and development in order to advance superconductivity to the next stages. The ISS Symposium is expected to serve as a venue for increasing our knowledge of superconductivity and for exchanging visions for future research and applications, through the presentation and discus of the latest research results. These proceedings also aim to summarize sion annual progress in high-Tc superconductivity in all fields.

Download or read book Effects of Gamma Radiation and Low Energy Electrons Beam on Semiconductor Thin Films written by Mehdi Souli and published by . This book was released on 2023-09-15 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research work has been continuously dedicated by the scientific community to improve or optimize the physical properties of thin films. In this present book, we bring into the attention an important research axis developed in our research group, i.e. the use of irradiation with intense gamma radiation and electron beam energy with the aim to improve and customize the structural, optical, morphological and electrical properties of thin film semiconductors for space and terrestrial photovoltaic applications, dosimetry of ionizing radiation and photocatalysis for the depollution of water contaminated by organic dyes. The number of worldwide scientific contributions and publications in this area of research is considered low compared to other research areas, hence the desire to contribute to developing and enriching this research area of thin film semiconductors. Our work was carried out in collaboration with the National Center for Nuclear Sciences and Technologies (CNSTN) in Tunisia, which owns the industrial equipment for gamma irradiation. An agreement was signed between the LPMC (define LPMC) laboratory and the CNSTN to carry out several gamma irradiation campaigns for several types of materials. Another collaboration was made with the COFICAB industrial company that produces electric cables, which is a subsidiary of the CHAKIRA group, to offer us an electron beam time with their low energy electron accelerator. Irradiation by ionizing radiation is widely used in food preservation to extend their storage or marketing periods and also for the sterilization of medical products. Among the outstanding industrial applications of electron beam irradiation is its use to improve the physical properties of the polymers making up the sheaths of electrical cables. In fact, the electrons emitted by the accelerators entrain free radicals in the polymers, the recombination of which leads to an improvement in their resistance to the high temperature of fires and to harmful solvents. In addition, many research works use irradiation to study the resistance of materials to intense nuclear radiation or to increase their life spans and for certain other materials to strengthen their nuclear waste storage capacities. Hence our motivation to use gamma radiation or electron beam irradiation to try to find improvements in the physical properties of semiconductor thin films used in the photovoltaic field or photocatalysis. Indeed, irradiation could be considered as a powerful tool to modify in a controlled way the electrical, structural, optical and morphological properties of these thin films. The choice of materials was motivated by their role played in optical windows, absorbers or buffer layers, which are commonly used in the new generation of photovoltaic cells. The two families of materials are the transparent conductive oxides (TCO), such as Fe-doped In2O3, and sulfur-based compounds, such as In2S3, Cu2ZnSnS4 and Sm-doped CaSO4. The synthesis and growth of these materials have been developed and optimized in our LPMC laboratory through previous research works. To the best of our knowledge, our work on the irradiation of thin films by gamma radiation of thin films of Cu2ZnSnS4, In2S3 and In2O3 doped with iron and fluorine is novel and the results are of great interest for the scientific community. The main objective of applying irradiation is to systematically control and improve the structural, optical, morphological, or electrical properties of thin films by applying very precise doses of gamma radiation or electron beams. Irradiation can cause structural defects in crystal lattices, generate excitations, change, or transform energy levels or even break atomic bonds, which can be used to tailor the properties of thin film semiconductors for specific applications.
Download or read book Thin Film Growth with Ions Clusters and Metal Compounds written by and published by . This book was released on 1995 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: The central theme of the project involved the interaction of ionized beams with solid surfaces. Such studies are relevant to materials synthesis problems because advanced manufacturing processes involve thin film growth and etching under conditions where energetic ions and clusters are present. While it is known that these ions play an important role, the details of their interactions are poorly understood. A significant part of the program during this funding period dealt with the development of instrumentation that would allow the formation of a beam of ionized clusters, the selection from that beam of those clusters that had a particular mass and energy, and then the deposition of those clusters onto a surface with full control over the parameters of deposition. The source was successfully built and tested. The goal was to study the atomic-scale processes of this ionized cluster beam deposition (ICBD). The plan was to use scanning tunneling microscopy to characterize the clusters that were deposited and to determine the effect on the surface as a function of cluster energy and cluster size. jg p.6.
