| Abstract: | The cathodic current-potential curves of CdTe electrodeposition were measused using a rotating disc electrode. It was observed that there was a good linear relation between the square root of rotating rates and the electrodeposition currents At various rotating rates,the ratio of current at -0.25 V to that at -0.50 V (vs. SCE) was close to 2/3. The X-ray diffraction analysis, XPS and AES showed that CdTe could be electrodepsited at a potential more positive than that for Cd electrodeposition. Based on these resul... |
