摘要
In this paper, AC measurements on lightly doped n-InP were carried out as a function of temperature down to about 16 K and at frequencies in the range from 120 Hz up to 10(5) Hz. The AC conductivity at low temperatures is of a single hopping nature following the universal law; sigma(omega) similar to omega(s), where the exponent, s, is temperature-independent. At relatively high temperatures (but still below the room temperature) the AC conductivity is of a multiple hopping nature.
