The results show that this novel structure can suppress the short channel effects （SCE）, the drain-induced barrier-lowering （DIBL） and improve the subthreshold performance in nanoelectronics application. The model is verified by numerical simulation. The model provides the basic designing guidance of gate stack strained Si on SGOI MOSFETs.展开更多
