Abstract: In this paper, we review and contrast some computational methodologies to investigate charge transport in low dimensional materials and devices. This includes ultra-scaled MOS devices as well as nanowires-based field effects transistors or carbon nanotubes-based emerging devices. After presenting the context of nanodevice simulation, the focus will be made on the limits for ballistic transport in these several types of nanodevices.

Keywords: charge transport; transistor simulation; Monte Carlo simulation; tight binding; non equilibrium green functions; Kubo approach; Landauer-Buttiker method; modelling; field effect transistors; ultra-scaled MOS devices; nanowires; carbon nanotubes; nanodevices; nanotechnology.
