Abstract. The theory of free-carrier absorption is given for a quasi one-dimensional semiconducting structures in a quantizing magnetic field for the case when carriers are scattered by polar optical phonons and acoustic phonons and the radiation field is polarized perpendicular to the magnetic field direction. The usual resonance condition , where P is an integer and w0 and wc are the optical-phonon frequency and cyclotron frequency, respectively, becomes with equal to . The magnetic field dependence of the absorption for the transverse configuration can be explained in terms of phonon-assisted transitions between various Landau levels of carriers.
Keywords: quantizing magnetic field, quantum well.
