Al/p-Si/Al metal/oxide layer/semiconductor or so-called metal/insulating layer/semiconductor (MIS) structures with interfacial native oxide layer are experimentally determined. For this structure, p-Si semiconductor with 1-10 Ω-cm resistivity was used as base material. The native oxide SiO2 layer was formed on the front polished surface the p-Si wafer in the laboratory environment. In order to obtain diode parameters, it was determined the experimental frequency admittance characteristics of the Al/p-Si MIS structure from commonly used capacitance-voltage (C-V) conductance-voltage (G-V) measurements at different frequencies, and parameters such as the real 𝜀′ and imaginary dielectric 𝜀′′ constant, loss-tangent (𝜀′′/𝜀′), real 𝑀′ and imaginary electrical modulus 𝑀′′ and ac conductivity σac were calculated and interpreted.
