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 forrnlow-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”:null,”files”:[{“@type”:”File”,”id”:1580,”name”:”SISPAD-2014_Validity-MRT-LD-CS.pdf”,”bytes”:758066}],”tags”:[{“@id”:”/api/v1/download_tags/20″,”@type”:”DownloadTag”,”id”:20,”name”:”publication”},{“@id”:”/api/v1/download_tags/44″,”@type”:”DownloadTag”,”id”:44,”name”:”vsp”},{“@id”:”/api/v1/download_tags/60″,”@type”:”DownloadTag”,”id”:60,”name”:”innovation”}],”date”:”2014-09-11T00:00:00+02:00″,”authors”:”Z.
