THE DISPLACEMENT OF THE SELENIUM ATOM IN SINGLE-CRYSTAL ZINC SELENIDE BY ELECTRON BOMBARDMENT
Abstract
The fluorescence structure and the displacement energy of lattice atoms in single-crystal synthetic zinc selenide were investigated with a low-energy electron beam probe. Fluorescence peak intensities at 77 K were observed at 0.45, 0.46, 0.49, 0.525, 0.55, 0.64, 0.85, 1.0, 1.25, 1.65, 2.0, and 2.2 mu. The temperature dependence of 5 of the more prominent peaks was examined. The structured edge emission containing as many as 5 lines has also been observed. The threshold for the controlled growth of a broad 0.55 mu peak band was observed at 240 ! 10 kev, which corresponds to a maximum energy transfer to the selenium atom of 8.2 ev. Although positive evidence is lacking, the causing defect for the 0.55 mu band appears to be the selenium vacancy.
