Abstract(in English) X-ray diffraction (XRD) analysis, X-ray photoelectron spectroscopy (XPS) and energy dispersive X-ray spectroscopy using high-resolution transmission electron microscope (HRTEM-EDX) were used to detect p-type Cu-S compounds such as Cu_2S in p-type Cu-doped CdS (CdS:Cu) films fabricated by the vacuum deposition of CdS on thin Cu films on glass substrate. It was showed that Cu atoms were diffused throughout the films and that crystalline Cu-S compounds were not formed in the CdS:Cu films. ITO/p-CdS:Cu/n-CdS/Al diodes were fabricated by vacuum process. The diodes showed good rectification characteristics and light emission under a forward current at 77 K. The colors of emitted light changed within the range of blue-green to red depending on the Cu concentrations and Current density.
