The high-frequency conductivity of a thin semiconductor wire in the longitudinal magnetic field

The problem of high-frequency conductivity of a thin semiconductor cylindrical wire at arbitrary temperature in the longitudinal magnetic field is solved by the kynetic method. The charge carrier reflection from inner wire surface is assumed to be diffuse. The ratio between the mean free path of charge carriers and the wire radius is supposed to be arbitrary. The results obtained for limiting cases of degenerate and nondegenerate semiconductor were subjected to comparative analysis. (paper)
