STRUCTURAL AND MORPHOLOGICAL STUDIES OF SPRAY DEPOSITED UNDOPED AND IODINE DOPED CdTe NANOCRYSTALLINE THIN FILMS

摘要

Cadmium telluride (undoped and iodine doped) nanocrystalline thin films were prepared by spraying CdTe and CdTe:1 nanoparticles, dispersed in 1-butanol on the glass substrates. The nanoparticles were prepared using the solvothermal method. The presence of iodine in the films was confirmed by the sign of voltage generated (positive relative to the cold end) in the hot probe method and by XPS studies. The effects of iodine doping on the structural and surface morphology in these thin films are reported.
