项目摘要
:In recent years, advances in LSI technology based on the continuous scaling of metal-oxide-semiconductor (MOS) field-effect transistors (FETs) has enabled improvements in the switching speed,density,functionality, and cost of microprocessors. However,such downsizing now becomes a cause of reducing the device performance due to increasing leakage current and short channel effects. In this project,we have investigated, making use of a newly developed quantum transport simulator, the effectiveness of using the InAs/Si hetero-junction nanowire (NW) as a solution to the above problem,and influence of strain caused byhetero-junction on tunneling characteristics through hetero interface. As a result, the simulator enabled us to find that the InAs p-i-n structure shows most favorable characteristics in both the on-current and the sub-threshold slope and the p-Si-i-Si-n-InAs structure is the runner-up.
近年来,基于金属氧化物半导体(MOS)场效应晶体管(FET)的连续缩放的LSI技术的进步使得微处理器的开关速度、密度、功能和成本得以改进。然而,由于漏电流和短沟道效应的增加,这种小型化现在成为降低器件性能的原因。在本计画中,我们利用一个新发展的量子输运模拟器,研究使用InAs/Si异质接面奈米线(NW)作为解决上述问题的有效性,以及异质接面所造成的应变对异质界面隧穿特性的影响。结果表明,InAs p-i-n结构在导通电流和亚阈值斜率方面都表现出最好的特性,而p-Si-i-Si-n-InAs结构则处于第二位。
