Theory of defects in semiconductors

WebbWe present a quantitative theory to describe enhancement of defect reaction rates upon electron-hole recombination. The theory is based on the following mechanism: energy liberated upon nonradiative electron or hole capture is converted largely into vibrational energy that is initially localized in the vicinity of the defect. This vibrational energy can be … Webb24 aug. 2024 · Optically and magnetically active point defects in semiconductors are interesting platforms for the development of solid state quantum technologies. Their optical properties are usually probed by measuring photoluminescence spectra, which provide information on excitation energies and on the interaction of electrons with lattice …

WebbThe details of bound exciton systems vary as much as the many free exciton systems discussed by Knox ().To provide a basis for discussing data, we treat the system which proves particularly amenable to analysis (Hopfield 1964).Here the host crystal is a nonpolar isotropic semiconductor for which the simplest effective-mass theory is appropriate. Webb26 feb. 2011 · We discuss the application of state-of-the-art first-principles calculations to the problem of defects, impurities, and doping levels in semiconductors. Since doping problems are of particular relevance in wide-band-gap materials, we focus here on studies of ZnSe and GaN. depth upper cabinets https://artificialsflowers.com
