Conference paper


Magnetophonon resonances are studied in quantum wires with square confinement potential. Magnetoconductivity calculated by using the Kubo formula is found to have two components; one related to the current carried by electron hopping motion between the localized cyclotron orbits through electron-phonon interaction, and the other caused by the current carried by electron motion affected by the confinement potential. The latter, σ po, is found to be two orders of magnitude greater than the former, σ ep, around the fundamental resonance condition in the case of a GaAs quantum wire whose width is 200Å and barrier height is 100meV.
