ABSTRACT

Substrate plays a crucial role in preserving the superb operation performance of graphene FETs. In this proposal, we will systematically study the substrate impact and metal-graphene contact reliability on the electronic transport properties of graphene FETs. By combining CVD assembled graphene FET experiments with ab initio theory and NEGF electronic/thermal transport modeling of graphene transistors on various 2D (BN and fluorinated-graphene) and typical 3D silicon-based substrates, we study how the corrugated and terraced substrates change the effective carrier mobility, transconductance, leakage current, and gain of graphene FETs. The break-down mechanism of metal electrode-graphene contacts and ESD properties of graphene FETs will also be investigated. Our work will promote the high performance and reliability of graphene FETs on various substrates. More... »
