Notes:
Cu2ZnSnSe4 (CZTSe) thin films were grown on Corning glass 1737 by sequential methodsof sputtering deposition and selenization process. As-grown films showed that elemental Cu, Zn, andSn were in the nearly CZTSe stoichiometric ratio with Se-deficiency as detected by Energy DispersiveX-Ray spectrometry (EDX). In order to attain film stoichiometry, as-deposited films were subjectedto selenization process in tube furnace under Ar ambient at different selenization temperatures for10-60 min. It was found that compositions of binary compound in the sputtering target as well asselenization are critical for the growth of the CZTSe films. The structural characteristics of theselenized CZTSe films revealed a highly oriented stannite CZTSe phase with (112), (220/204) and(312/116) growth orientations and a CuSe secondary phase. By using 0.5% KCN solution, CuSesecondary phase could be totally etched from the CZTSe film surface
