High-frequency conductivity of a thin cylindrical semiconductor wire at arbitrary temperatures

The high-frequency conductivity of a thin straight semiconductor wire with a circular cross section is treated in the context of the classical kinetic theory. The calculation is conducted for an extrinsic semiconductor with a simple band structure at any degree of degeneracy. The relation between the wire radius and the mean free path of charge carriers is taken to be arbitrary. The diffuse mechanism of reflection of charge carriers from the wire boundary is considered.
