Final-state effects in the excitation spectra of deep impurities in semiconductors
Abstract
The excitation spectra of deep impurities have usually been interpreted in terms of transitions to continuum states having the same energy distribution and Bloch-like character as the perfect-crystal band states. Here we provide theoretical analysis and experimental evidence showing that deep-level spectra may in fact be dominated by bound and quasibound final states induced by the strong short-range impurity potentials. © 1980, All rights reserved.
