Dilute magnetic semiconductor of ZnCoSe thin films: Structural, optical, and magnetic characteristics

A series of Zn1−xCoxSe (x = 0, 0.025, 0.050, 0.075, and 0.100) films using were evaporated (thickness of 1 μm) using electron beam gun. The effect of Co doping on the structural, optical, and magnetic properties has been investigated. X‐ray diffraction studies confirm formation of zinc blend structu...
