Although not always fully justified, it has been very practical in simulating transport in bulk and in direction quantity low-dimensional carrier gases alike. We review the assumptions behind the MRT, quantify the error introduced by its usage for low-dimensional carrier gases, and point out its weakness in accounting for inter-subband interaction, occurring specifically at low inversion densities.”,”level”:null,”doi”:”10.1109/sispad.2014.6931593″,”status”:”published”,”remarks”:”PrimAuthor: Z.
