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. 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 … Webb20 maj 2024 · All semiconductors, whether by design or by accident, contain defects.
