Abstract

In this paper, we report the effect of source/drain metal contacts on the electrical behavior of GeOI MOSFETs. The band diagram and current-voltage characteristics of the MOSFET are obtained using SILVACOATLAS, a 2D numerical device simulator, for various metals having a range of work function values. Our investigation reveals that the device using metals having a work function value more than 5 eV exhibits enhanced ON current, transconductance, intrinsic voltage gain, and also reduced subthreshold slope and OFF current.
