Magnetophonon resonances of quantum wires in tilted magnetic fields
The magnetoconductivity of parabolic quantum wires in strong tilted magnetic fields, associated with the magnetophonon resonance effect, is obtained analytically for optical-phonon scattering, by taking the linear-response limit of the results of the nonlinear-response theory developed previously. Neglecting the coupling Hamiltonian term ∼BxBzxz, since its contribution to the total electron energy is minor, the results for the magnetophonon resonance effect display two different periods of oscillation as a function of the strength and direction of the magnetic field and the confinement frequencies. In particular, it is shown that the direction of the magnetic field plays a significant role in determining the relaxation rates and the magnetoconductivity related to the magnetophonon resonances. © 1994 The American Physical Society.
