Electron Transport in Schottky Barrier CNTFETs
24 Oct 2017   Contributor(s):: Igor Bejenari
A given review describes models based on WentzelKramersBrillouin approximation, which are used to obtain IV characteristics for ballistic CNTFETs with SchottkyBarrier (SB) contacts. The SB is supposed to be an exponentially or linearly decaying function along the channel. The ...

Modeling of Interribbon Tunneling in Graphene
