Abstract

Nanocrystalline CuS thin films were fabricated using a metal organic deposition technique taking Cu(SOCCH(3))(2)Lut(2) as the precursor. X-ray diffraction (XRD) technique, field emission scanning electron microscopy (FESEM), atomic force microscopy (AFM), UV-vis absorption spectroscopy, photoluminescence spectroscopy (PL) and Raman spectroscopic techniques were applied for characterization and found that the deposited CuS films were of `covellite' phase with an average particle size of 18 nm. Optical measurements showed significant amount of ``blue shift'' in the band gap energy. Hall measurements of the films showed p-type conduction nature with a carrier concentration in the range 10(12)-10(13) cm(-3).
