| 摘 要： | Size quantized nanocrystalline semiconductor thin films have attracted considerable interest in the photoelectrochemical studies1,2. In this paper, we report a pronounced size quantization in nanocrystalline CdTe thin films which is less extensively studied.Nanocrystalline CdTe thin films were electrodeposited on conducting glass by asymmetric rectangular pulse in dimethylsulfoxide solution containing 6 mmol/L Te, 0.75 mmol/L Cd(ClO4)2, 18 mmol/L triphenylphosphine and 0.1 mol/L LiClO4 a…

| Abstract: | Nanocrystalline CdTe thin films were prepared by asymmetric rectangular pulse electrodeposition in organic solution at 110(C. STM image shows a porous network morphology constructed by interconnected spherical CdTe crystallites with a mean diameter of 4.2 nm. A pronounced size quantization was indicated in the action and absorption spectra. Potentials dependence dual conductive behavior was revealed in the photocurrent-potential (I-V) curves. |
