Characteristics of proton-induced point-defects for electron energy loss and optical absorption

ORAL

Abstract

We report the results of our investigation on the effects due to point defects on the loss of either energies of incident electron beams or photons on a quantum well. Many body effects and its consequences in the structure are included through defect-induced vertex corrections to the bare polarizability of electrons within the ladder approximation, and the intra- and inter-layer screening in the random-phase approximation. Our principal focus has been directed toward obtaining a wide range of numerical results for effects due to defect on both energy- the loss and optical-absorption spectra. The yielded outcomes from our simulations could provide specific designs of optoelectronic quantum devices that will be operated in space research with radiation-hardening protection.
