Abstract

IWCE 2015 presentation.

The quality of contacts between metals and two- dimensional materials is a critical aspect for the performance of transistors based on two-dimensional materials. In this talk we focus on an approach to multiscale modeling of graphene- metal contacts, considering both chemisorbed and physisorbed materials. We show that it is possible to use density functional simulations of contacts to extract a set of physical properties that enable accurate device-level simulations at a higher level of abstraction. We also show that – properly evaluated - the intrinsic conductance of graphene- metal contacts is higher than that predicted in previous studies.
