“…The binary cadmium chalcogenides, Cd X ( X = S, Se, Te), and the ternary semiconducting compounds, AB 2 X 4 ( A = Cd, Zn, Hg; B = Al, Ga, In; X = S, Se, Te) are investigated for possessing a wide bandgap and application in the photoluminescence and optoelectronic devices . The electrophotographic layers of these semiconductors illustrate a photographic distinction with high quality and great resolution .…”
