Reduction of metal-graphene contact resistance by direct growth of graphene over metal
관리자2013-08-08조회 4804
The high quality contact between graphene and the metal electrode is a crucial factor in
achieving the high performance of graphene transistors. However, there is not sufficient
research about contact resistance reduction methods to improve the junction of metal-graphene.
In this paper, we propose a new method to decrease the contact resistance between
graphene and metal using directly grown graphene over a metal surface. The study found
that the grown graphene over copper, as an intermediate layer between the copper and the
transferred graphene, reduces contact resistance, and that the adhesion strength between graphene
and metal becomes stronger. The results confirmed the contact resistance of the metalgraphene
of the proposed structure is nearly half that of the conventional contact structure.
