2014 m. Nr. 3 Deposition and characterization of copper sulphide layers on the home-made polycarbonate plates
Copper sulphide layers were deposited on the home-made polycarbonate (PC) plates by the chemical bath deposition (CBD) method. The layers were characterized by X-ray diffraction (XRD), optical microscopy (OM), Fourier transform infrared (FT-IR) spectroscopy. X-ray diffraction analysis showed that the layers are composed of covellite (CuS) and chalcocite (Cu2S) phases with a hexagonal and a monoclinic unit cell, respectively. The spherical particles of Cu2-xS with a size range of 1–27 μm in diameter were deposited depending on the number of deposition cycles. The room temperature sheet resistance of Cu2-xS layers deposited on PC plates is 1.13 kΩ/cm2 after the fourth deposition cycle.
