Structure and optical properties of thin films CZTS obtained by the RF magnetron sputtering

摘要

Structure and optical properties of thin films cadmium CZTS produced by RF magnetron sputtering of preliminarily synthesized material are studied. Transmission and reflection coefficients are studied in a range from 0.4 to 4.0 urn. On the basis of the experiments of transmission and reflection coefficients the index of refraction and optical width of the bandgap of thin films under study are measured by the method based on measuring of the transmission and reflection coefficients. It was found out that there are direct interzone optical transitions in the thin films under study.
