We report on the influence of the low deposition temperature of ZnO as semiconductor layer on the electrical characteristics of metal-insulator-semiconductor (MIS) structures. The ZnO films were deposited by radio frequency (RF) magnetron sputtering with variation of temperature from 40°C, 60°C, 80°C, 100°C and 120°C. PMMA were used as insulator layer in the MIS structures. It is found that the ZnO films grown at 120°C has better crystallinity compared to other temperature. I-V characteristics results shown that the different deposition temperature of ZnO films affect the performance of MIS.

X-ray photoelectron spectroscopy, Auger electron spectroscopy and ellipsometry measurements were performed at Cr-SiOx, and Yb-SiOx interfaces, which are being considered for metal/insulator/semiconductor (MIS) solar cell applications. These measurements have led to a knowledge of instability mechanisms associated with MIS solar cells. The dynamics of the metal-oxide interface reduce the effective thickness of the insulating SiOx layer. Typically, in a 3 week period after fabrication the oxide thickness decreases by about 2 Å for ytterbium MIS structures and by less than 1 Å for chromium MIS structures. A structural equilibrium is reached thereafter. To explore further the dependence of MIS Schottky barrier heights on oxide thickness variations (from about 5 to 20 Å) a comprehensive charge balance analysis was performed at a general MIS interface. This theoretical study supports experimental data on barrier heights and also on instabilities. In addition, the application of the theoretical model to the experimental barrier heights has yielded quantitative information regarding the density of interface states at the SiOx,–Si interface.
