Structure and optical properties of polycrystalline Cd1-xZnxTe thin films prepared by simultaneous evaporation

Cd^sub 1-x^Zn^sub x^Te films were deposited by simultaneous evaporation of CdTe and ZnTe. These Cd^sub 1-x^Zn^sub x^Te films were of cubic phase, and strongly (1 1 1) oriented as deposited. Predominant direct optical transitions were observed and the band gap varied with zinc content in a non-linear...

Description
Summary:Cd^sub 1-x^Zn^sub x^Te films were deposited by simultaneous evaporation of CdTe and ZnTe. These Cd^sub 1-x^Zn^sub x^Te films were of cubic phase, and strongly (1 1 1) oriented as deposited. Predominant direct optical transitions were observed and the band gap varied with zinc content in a non-linear way. A structure development of CdS/CdTe/ZnTe : Cu solar cells with a Cd^sub 1-x^Zn^sub x^Te buffer layer was proposed.[PUBLICATION ABSTRACT]
