| چکیده | ||
| This paper includes description of fabrication and characterization of two Schottky diodes differ in substrate material (n-type and p-type black Silicon). Schottky diodes were composed of (Ag /B-Si/n-Si/Al and Ag/B-Si/p-Si/ Al) respectively. Etching was achieved both electrochemical and photo--electrochemical etching processes. Different etching times and etching current densities were applied. Ag for front contact and Al for back contact were deposited by thermal evaporation method. I-V characteristics were plotted for the diode in dark forward and backward biasing at room temperature. The ideality factor and barrier height values were obtained. The barrier height values was(0,33-0,36) eV and the saturation current values (6,86-7,05) for the diode samples were obtained from the current-voltage (I-V) curves , The ideality factor (\textit{n})\textbf{ } values was(27.47-35.61), Schottky diodes at the Ag/BS or the dual metal-semiconductor junctions (Ag/BS/c-Si and c- Si/Al), of a diode ideally exhibit Ohmic features). | ||
