Electrical properties of CuInTe2(1-x)S2x thin film by spray pyrolysis

Thin films of CuInTe2(1-x)S2x were grown by spray pyrolysis and develop thin films on glass substrate at 350C by varying proportion x in the range of 0.25. Aqueous solutions of cupric chloride, indium tri-chloride, thio-urea and tellurium tetra-chloride mixed in proper composition x and studies their electrical properties of all these films. The resistivity of the films was measured for temperature ranging from 77 K to 473 K. The activation energies values were calculated from Arrhenius plot. At very low temperature a variable range hopping conduction mechanism appears to be operative. Surface of thin films has been studied by Scanning Electron Microscope. Copyright © 2018 VBRI Press.
