Özet

The chemical composition of the electrodeposited undoped and F-doped ZnO (FZN) rods was investigated by X-ray photoelectron spectroscopy (XPS). These results confirmed the existence of F as a doping element into ZnO crystal lattice. The p-Si/n-ZnO and p-Si/n-FZN heterojunction diodes were fabricated and their electrical properties were investigated. Some parameters belong to these diodes such as ideality factor (n), barrier height (phi(B)), and series resistance (R-s) which were calculated from the current-voltage (I-V) curves that exhibited rectifying behavior by using thermionic emission theory, Norde's function, and Cheung's method. There is a good agreement between the diode parameters obtained from different methods.
