Paper Abstract

CdTe needle-like crystals were grown by CTR method in CdTe-Br system. Their resistivity is changed from 10 to 1000 (Omega) (DOT)cm depending on crystal diameter: it increases with the increase of wire diameters from 50 to 250 micrometer. Specimens with (rho) > 10 (Omega) (DOT)cm are observed to be photosensitive at 300 K. Photoconductivity spectrum is shown to depend on the whisker diameters. A model explaining the whisker electronic and photoelectrical parameters and their dimensional dependencies is discussed. This model is based on account of the surface states.
