Metal/graphene contact as a performance Killer of ultra-high mobility graphene analysis of intrinsic mobility and contact resistance

Graphene with a high carrier mobility of more than 10,000 cm

has attracted much attention as a promising candidate of future high-speed transistor materials. The contact resistance (RC) between graphene and metal electrodes is crucially important for achieving potentially high performance of graphene from both physics and practical viewpoints. This paper discusses metal/graphene contact properties by separating from the intrinsic conduction of graphene.
