Hydrochemical synthesis, structure, semiconductor properties of films of substitutional Pb 1 - XSn xSe solid solutions

Abstract

The region of lead and tin selenide co-deposition using selenourea has been examined by calculation of the ionic equilibrium in the citrate-ammonia system. The formal kinetic equations for the rates of formation of the lead and tin selenides have been determined. Thin films of substitutional Pb 1 - xSn xSe (0 < x < 0.093) solid solutions were produced from aqueous solutions. The composition, crystal lattice spacing, thermal band gap and conductivity of the films have been analysed. © 2012 Elsevier B.V. All rights reserved.
