On the Current Drive Capability of Low Dimensional Semiconductors: 1D versus 2D

摘要

Low-dimensional electronic systems are at the heart of many scaling approaches currently pursuit for electronic applications. Here, we present a comparative study between an array of one-dimensional (1D) channels and its two-dimensional (2D) counterpart in terms of current drive capability. Our findings from analytical expressions derived in this article reveal that under certain conditions an array of 1D channels can outperform a 2D field-effect transistor because of the added degree of freedom to adjust the threshold voltage in an array of 1D devices.Electronic supplementary materialThe online version of this article (doi:10.1186/s11671-015-1134-6) contains supplementary material, which is available to authorized users.
