Theory of the free-carrier absorption in quantum wires with boundary roughness scattering
A theory of free carrier absorption is given for quantum wires when carriers are scattered by boundary roughness and the radiation field is polarized along the length of the wire. The free-carrier absorption coefficient is found to be an oscillatory function of the photon frequency and of the wire w...
