Carrier transport and stress engineering in advanced nanoscale transistors from (100) and (110) transistors to carbon nanotube FETs and beyond

Carrier transport in advanced MOSFETs is reviewed. First, electron and hole mobility in (110) MOSFETs are compared with those in (100) MOSFETs. Stress engineering is discussed in terms of energy split and effective mass due to the stress. The optimization of multi-gate MOSFET structure is then considered. As an example of ballistic MOSFETs, the performance and stress engineering of CNT FETs with doped junctions are investigated.
