摘要
Results of capacitance-voltage and current-voltage measurements performed on Ti/porous silicon (PS)/p-Si diode structures are presented. A 5-10 increase of conductivity and capacity has been observed at f < 10000 Hz in response to the moisture change from 0 to 50%. Model of Schottky contact on thin PS layer with the charge carriers inside of pores and PS/Si interface is applied to explain the frequency dependence of conductivity/capacity as well as moisture effect.
