Abstract
A detailed analysis of PhotoLuminescence spectroscopy (PL) on undoped and Te- and Zn-doped samples of high-quality GaSb is presented. Temper ature variations of PL peak position and intensity have been used to f ind the origin of various transitions. The PL peaks of undoped samples have been assigned to unintentional impurities, native defects and ex citons bound to the defect. The zinc- and tellurium-related peaks have been identified and the effect of doping concentration on their posit ion and PL efficiency have been studied.
