Download or read book Energetics and Dynamics in Quantum Confined Semiconductor Nanostructures written by Jessica Hoy and published by . This book was released on 2013 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ability to tune the band-gap energies of semiconductor quantum dots, nanoplatelets, and quantum wires, their significant absorption cross sections, and high photoluminescence quantum yields make these nanostructures promising moieties for use in optoelectronic devices, solar concentrators, chemical sensors, and biological labels. The variable dynamics of the electron-hole pairs that occur within semiconductor nanostructures, however, can complicate the utility of these devices. The variability of the dynamics is born from the different paths accessible for the charge carriers to undergo. In this work, three pathways are proposed to be of primary consequence, namely, electronic intraband relaxation, coupling to surface-mediated processes, and tunneling to the external environment. The relative dominance of these paths will vary from sample to sample. More importantly, within a sample, the contributions of the available pathways are found to change with changes in excitation energy. To this end, I investigated the dependence of the ensemble photoluminescence (PL) quantum yields (QYs) on excitation energy for numerous semiconductor nanoparticles with quantum confinement in varying dimensions. A strong dependence of the PL QY on excitation energy is observed in quantum dots (QDs), nanoplatelets (NPLs), and quantum wires (QWs). The highest PL QYs are within the first 300 meV above the band edge, and there is a severe drop in the PL QY towards the highest excitation energies investigated, ~3.1 eV. These high PL QYs are 91 % for CdSe/ZnS QDs, 24 % in CdSe NPLs, which are dispersed in toluene and 25 % in CdTe/CdS QWs, which is dispersed in TOP. These values drop to 12, 8, and 8 % by 3.1 eV, respectively. There are some recognized trends to the shape of this dependency. Local minima in PL QY values occur when intraband relaxation is restricted and ligand or surface mediated transitions are available. These variations in PL QY are reduced when a shell is added to produce a type-I heterostructure. This trend is realized in both QDs and QWs. However, QWs are more weakly confined systems with large surface areas. Their saw-like densities of states that result from the long, unconfined dimension of the QWs and increased valence state mixing yields a higher density of states which leads to a smoother PL QY dependence of the excitation energy. The minimal undulations in the PL QYs that do still exist in these QWs, are further minimized with the addition of a shell to create a type-I heterostructure. Conversely, the pseudo-2D confinement and atomic flatness of NPLs results in narrow, discrete bands of states separated by large energies, ~ 200 meV. This electronic structure restricts intraband relaxation and promotes coupling to other pathways that sponsor non-radiative recombination even more efficiently than QDs. In all samples, exciting with high energies severely diminishes PL QYs as these energies generate highly excited charge-carriers that can access solvent/environmental pathways.

Download or read book CMOS Front End Materials and Process Technology Volume 765 written by Materials Research Society. Meeting and published by . This book was released on 2003-09-12 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the future, because fundamental materials and process limits are being approached, continued transistor scaling will not be as straightforward. Future complementary metal-oxide semiconductor (MOS) transistors will require high-permittivity (high-k) gate dielectrics and metal gate electrodes, as well as low-resistance ultrashallow junctions, in order to meet the stringent specifications of the International Technology Roadmap for Semiconductors. Techniques to improve transconductance and drive current may also be required. Process integration issues must be solved, and reliability must be assured, before any new material or processing technique can be used in IC manufacture. A further complication is that the key challenges will differ according to application. This book reports research results from industry, government labs and academia covering a wide scope of front-end process issues for future CMOS technologies. Topics include: advanced materials and structures; high-k dielectrics; advanced gate stack materials; heterogeneous integration and strained Si technologies; ultrashallow junction technology; strained Si and source/drain technology; and laser annealing and silicide processes.
Download or read book Granular Material based Technologies written by Surajit Sen and published by . This book was released on 2003 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: The past decade has seen an explosive growth of interest in the physics of granular materials. Granular media are comprised of macroscopic objects with internal degrees of freedom. Granular assemblies exhibit phenomena that incorporate the properties of traditional solids, liquids and gases, making it a unique state. In many ways, the granular state is a generalized state of matter. This new volume from the Materials Research Society brings together researchers from many countries and disciplines to assess issues and problems concerned with the collective behavior of granular assemblies as encountered in the context of various applications. In particular, these applications include ceramic science, shock propagation and absorption, design and maintenance of stable natural and artificial structures, processing of pharmaceuticals, and self-assembly processes associated with the synthesis of ultrahigh-density magnetic tapes. The volume should be of value to researchers involved in exploring granular material-based technologies, and is expected to stimulate further research in this arena. Topics include: electromagnetic fields; structural issues; flow behavior; and dynamical problems.

Download or read book Materials Inspired by Biology written by James L. Thomas (Ph. D.) and published by . This book was released on 2003 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Continued interest in the field of biologically inspired materials is strongly motivated by the fact that the nanoscale and microscale organization found in biological materials often leads to exceptional macroscopic materials properties. The ability to mimic these structures should lead to new synthetic materials with similarly remarkable behavior in both biomedical and materials arenas. This has led to an enormous amount of research in a variety of materials areas, including those aimed at: 1) unique ceramics or composites for use in biomaterials, magnetic and optical applications; 2) self-assembled biopolymeric systems for use in biomaterials and biosensor applications; and 3) colloidal and amphiphilic systems for application in biomedicine, nanotechnology and biosensors. Accordingly, this volume brings together a broad range of researchers whose interests span the full breadth of biology, and in addition, those who find different inspiration in biology itself. For some, that inspiration is in the creation of new materials that have important biological (especially biomedical) applications. For others, it is the imitation of the behavior of a biological material, molecule or process that is of interest. Finally, with increasing frequency, researchers are drawing inspiration from the synthetic pathways that biology uses, exploiting these pathways, and modifying them chemically or genetically to make entirely novel molecules and materials. Biologically inspired materials is a rapidly evolving arena of materials science research, and the work presented here reflects recent advances and new perspectives in the field. Topics include: tissue engineering and biomaterials; novel biomimeticand bioinspired polymers; biomineralization, colloidal and templated materials; and amphiphilic membranes and surfaces.
