摘要：
In this study, (CuO doped PVA) composite material was deposited using spin coating technique on n-Si and the Au/CuO-PVA/n-Si Metal/Polymer/Semiconductor type Schottky Barrier Diodes (MPS type SBDs) were fabricated. The electrical measurements of Au/CuO-PVA/n-Si SBDs were realized in the dark and under various UV (365 nm) light intensities ranging from 50 to 250 mW/cm(2). The basic parameters of the MPS type SBDs such as leakage current (I-0), zero bias barrier height (Phi(B0)), barrier height (Phi(B)), ideality factor (n), series resistance (R-s), shunt resistance (R-sh), rectification rate (RR), photocurrent (I-pc) and surface states (N-ss) were obtained Current-Voltage (I-V) plot based on Thermionic Emission (TE) theory, and Norde function depending on the UV light intensity. As the light intensity increases, RR, R-sh, Phi(B0), and Phi(B) decreased but the n and I-0 increased. In addition, the increase of UV light intensity caused the increase of photocurrent in MPS type SBDs and thus MPS type SBDs exhibited more ohmic behavior.
