II-VI semiconductor compound

II-VI semiconductor compounds are compounds composed of a metal from either group 2 or 12 of the periodic table (the alkaline earth metals and group 12 elements, formerly called groups IIA and IIB) and a nonmetal from group 16 (the chalcogens, formerly called group VI). These semiconductors crystallize either in the zincblende lattice structure or the wurtzite crystal structure. They generally exhibit large band gaps, making them popular for short wavelength applications in optoelectronics.
