Magnetophonon and electrophonon resonances in quantum wires

Based on the formalism developed previously [Phys. Rev. B 48, 9126 (1993)], magnetophonon resonances and electrophonon resonances in quantum wires are investigated for various confinement potentials. The occupation of several electric subbands due to these confinement potentials leads to electrophonon resonances and a splitting and shift of magnetophonon resonance peak positions. The dependence of both resonance peak positions on the magnetic field, the thickness of the well, the confinement frequency, and the bias field is shown explicitly.
