Book Direct Simulation of Ion Beam Induced Stressing and Amorphization of Silicon

Download or read book Direct Simulation of Ion Beam Induced Stressing and Amorphization of Silicon written by and published by . This book was released on 1999 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using molecular dynamics (MD) simulation, the authors investigate the mechanical response of silicon to high dose ion-irradiation. The authors employ a realistic model to directly simulate ion beam induced amorphization. Structural properties of the amorphized sample are compared with experimental data and results of other simulation studies. The authors find the behavior of the irradiated material is related to the rate at which it can relax. Depending upon the ability to deform, the authors observe either the generation of a high compressive stress and subsequent expansion of the material, or generation of tensile stress and densification. The authors note that statistical material properties, such as radial distribution functions are not sufficient to differentiate between the different densities of the amorphous samples. For any reasonable deformation rate, the authors observe an expansion of the target upon amorphization in agreement with experimental observations. This is in contrast to simulations of quenching which usually result in a denser structure relative to crystalline Si. The authors conclude that although there is substantial agreement between experimental measurements and simulation results, the amorphous structures being investigated may have fundamental differences; the difference in density can be attributed to local defects within the amorphous network. Finally the authors show that annealing simulations of their amorphized samples can lead to a reduction of high energy local defects without a large scale rearrangement of the amorphous network. This supports the proposal that defects in a-Si are analogous to those in c-Si.

Available in PDF, EPUB and Kindle. Book excerpt: Materials science is the prime example of an interdisciplinary science. It - compasses the ?elds of physics, chemistry, material science, electrical en- neering, chemical engineering and other disciplines. Success has been o- standing. World-class accomplishments in materials have been recognized by NobelprizesinPhysicsandChemistryandgivenrisetoentirelynewtechno- gies. Materials science advances have underpinned the technology revolution that has driven societal changes for the last ?fty years.

All fall in the technology domain. In every case proposed solutions begin with new forms of materials, materials processing or new arti?cial material structures. Scientists seek new forms of photovoltaics with greater e?ciency and lower cost. Water purity may be solved through surface control, which promises new desalination processes at lower energy and lower cost. Revolutionary concepts to extend the information revolution reside in controlling the “spin” of electrons or enabling quantum states as in quantum computing. Ion-beam experts make substantial contributions to all of these burgeoning sciences.

Book Ion Solid Interactions for Materials Modification and Processing  Volume 396

This book was released on 1996-05-23 with total page 940 pages. Available in PDF, EPUB and Kindle. Book excerpt: Several beam-solid interaction techniques have been developed that can either stand alone or be used in connection with others for materials processing, for fabrication of devices with enhanced electro-optical and mechanical properties, and with enhanced resistance to corrosion and erosion. For example, advances in focused ion beams (FIB) have brought out-of-reach ideas and applications to fruition. This book from MRS focuses on the developments in ion-beam-assisted processing of materials and reviews successful applications of the techniques. Topics include: fundamentals of ion-solid interactions; ion-beam mixing; radiation damage; insulators and wide bandgap materials; polymers; optical materials; plasma and ion-assisted techniques; metals and tribology; focused ion beams; fundamental semiconductor processing and compound semiconductors.

Book Ion Beam Modification of Materials

Download or read book Ion Beam Modification of Materials written by J.S. Williams and published by Newnes. This book was released on 2012-12-02 with total page 1157 pages. Available in PDF, EPUB and Kindle. Book excerpt: This conference consisted of 15 oral sessions, including three plenary papers covering areas of general interest, 22 specialist invited papers and 51 contributed presentations as well as three poster sessions. There were several scientific highlights covering a diverse spectrum of materials and ion beam processing methods. These included a wide range of conventional and novel applications such as: optical displays and opto-electronics, motor vehicle and tooling parts, coatings tailored for desired properties, studies of fundamental defect properties, the production of novel (often buried) compounds, and treating biomedical materials. The study of nanocrystals produced by ion implantation in a range of host matrices, particularly for opto-electronics applications, was one especially new and exciting development. Despite several decades of study, major progress was reported at the conference in understanding defect evolution in semiconductors and the role of defects in transient impurity diffusion. The use of implantation to tune or isolate optical devices and in forming optically active centres and waveguides in semiconductors, polymers and oxide ceramics was a major focus of several presentations at the conference. The formation of hard coatings by ion assisted deposition or direct implantation was also an area which showed much recent progress. Ion beam techniques had also developed apace, particularly those based on plasma immersion ion implantation or alternative techniques for large area surface treatment. Finally, the use of ion beams for the direct treatment of cancerous tissue was a particularly novel and interesting application of ion beams.

This book was released on 1997-05-29 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first particle accelerators were built in the early 1930’s. For a long time, these devices were used exclusively by nuclear physicists. In the 1960’s, extensive developments in measuring techniques occurred, mainly as a result of newly developed semiconductor devices. Further strong interest arose from the semiconductor industry, and ion implantation became widely accepted as being the ultimate tool for Si-based device fabrication.

Book Silicon Molecular Beam Epitaxy

Available in PDF, EPUB and Kindle. Book excerpt: This subject is divided into two volumes. Volume I is on homoepitaxy with the necessary systems, techniques, and models for growth and dopant incorporation. Three chapters on homoepitaxy are followed by two chapters describing the different ways in which MBE may be applied to create insulator/Si stackings which may be used for three-dimensional circuits. The two remaining chapters in Volume I are devoted to device applications. The first three chapters of Volume II treat all aspects of heteroepitaxy with the exception of the epitaxial insulator/Si structures already treated in volume I.

Book Molecular Dynamics Simulations of Disordered Materials

Download or read book Molecular Dynamics Simulations of Disordered Materials written by Carlo Massobrio and published by Springer. This book was released on 2015-04-22 with total page 540 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a unique reference work in the area of atomic-scale simulation of glasses. For the first time, a highly selected panel of about 20 researchers provides, in a single book, their views, methodologies and applications on the use of molecular dynamics as a tool to describe glassy materials. The book covers a wide range of systems covering "traditional" network glasses, such as chalcogenides and oxides, as well as glasses for applications in the area of phase change materials. The novelty of this work is the interplay between molecular dynamics methods (both at the classical and first-principles level) and the structure of materials for which, quite often, direct experimental structural information is rather scarce or absent. The book features specific examples of how quite subtle features of the structure of glasses can be unraveled by relying on the predictive power of molecular dynamics, used in connection with a realistic description of forces.
