摘要：

In this research, we report on the measurement of the capacitance-voltage (C-V) characteristics Al / ZnO / p-Si / Al Schottky diode at room temperature and in dark condition fabricated by spray pyrolysis process. C-V characteristics, within the range of frequencies 5 kHz-5 MHz, are investigated and microelectronic parameters are extracted. Donor density and diffusion potential vary with frequency from 15 to 28 1014 cm - 3, 0.21 to 0.45 V. Besides, the interface state density of Al /ZnO / pSi/Al Schottky is determined and found to be 1012 (eV.cm(2))(-1). Calculated at 1 MHz, the interfacial layer thickness and depletion layer width are of 760 angstrom and 0.28 m.
