Synthesis and properties of thin film ZnCuTe semiconductors

Electrodeposition in aqueous solution was used to prepare p-ZnCuTe semicond uctors in thin film form for photovoltaic applications. Formation of the te rnary compound having the cubic structure of ZnTe was achieved upon anneali ng at 400 degreesC. The optical characteristics of the film, in terms of op tical adsorption and energy gap, were found to depend upon the Cu content i n the film. This latter also influences sheet resistivity and majority carr ier concentration values.
