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 ...

27 Jun 2013   Contributor(s):: Jing Wang
As the conventional silicon metaloxidesemiconductor fieldeffect transistor (MOSFET) approaches its scaling limits, many novel device structures are being extensively explored. Among them, the silicon nanowire transistor (SNWT) has attracted broad attention from both the semiconductor industry...

Exploring New Channel Materials for Nanoscale CMOS
27 Jun 2013   Contributor(s):: Anisur Rahman
The improved transport properties of new channel materials, such as Ge and IIIV semiconductors, along with new device designs, such as dual gate, tri gate or FinFETs, are expected to enhance the performance of nanoscale CMOS devices. Novel process techniques, such as ALD, high# dielectrics,...

Physics and Simulation of QuasiBallistic Transport in Nanoscale Transistors
27 Jun 2013   Contributor(s):: JungHoon Rhew
The formidable progress in microelectronics in the last decade has pushed thechannel length of MOSFETs into decanano scale and the speed of BJTs into hundreds of gigahertz. This progress imposes new challenges on device simulation as the essential physics of carrier transport departs that of...

Landauer Approach to Thermoelectrics
21 Jun 2013   Contributor(s):: Changwook Jeong
Many efforts have been made to search for materials that maximize the thermoelectric (TE) figure of merit, ZT, but for decades, the improvement has been limited because of the interdependent material parameters that determine ZT. Recently, several breakthroughs have been reported by applying...
