Abstract
A study of the cathodoluminescence edge emission spectrum of zinc telluride at liquid helium temperatures after bombardment with monoenergetic electrons in the 100 to 500 keV energy range has been made. Production of a sharp emission at 2.362 eV after electron radiation damage of p type zinc telluride at 77 K allowed the determination of an energy threshold at 300 keV, which is assigned to the displacement of tellurium atoms. An electron of 300 keV is capable of transferring a maximum of 6.7 eV to a tellurium atom.Keywords
