When the confinement in a quantum wire is such that the spacing between subbands is equal to the optic phonon energy, a situation occurs in nonequilibrium conditions analogous to the longitudinal magnetophonon effect where due to phonon resonance an upper subband population is enhanced with respect to that of the lower subband. An investigation of the case in which a third intermediate subband is located slightly below the upper subband is reported. Two different quantum wire structures are considered. A Monte Carlo simulation of these structures at room temperature, including polar optic and acoustic phonon scattering, is used to obtain the distribution functions. Results for three distinct population inversions are shown.
