Abstract
A Ni/n-Si Schottky barrier diode was produced by electrodeposition technique from the electrolyte containing nickel ions
under galvanostatic control. The deposition was carried out in a three-electrode cell at room temperature. The electrical
characteristics of the Schottky diodes have been investigated using current-voltage (I-V) and capacitance-voltage (C-V)
measurements. Ni/n-Si/AuSb diode current-voltage characteristics display low reverse bias leakage currents. The barrier
height and ideality factor (n) were obtained 0.60 eV and 3.28 respectively. The high ideality factor value was attributed to
oxide layer at the metal semiconductor interface..
