We investigate carrier transport in multi subband quasi one-dimensional (1D) structures. The Monte Carlo simulation shows that due to the lack of angular randomization during scattering processes the electron system becomes rapidly nonlinear in the presence of optic phonon scattering for fields as low as 100 V/cm at room teperature. In 1D multiband systems, when the separation between quantized levels is equal to the polar optic phonon energy, resonances similar to magneto-phonon effects occur with intersubband population inversion and the possibility of far infra-red stimulated emission.
