ABSTRACT
Formation of high-quality electrical and thermal contacts between nanostructured materials such as carbon nanotubes or graphene and metal electrodes is one of the fundamental issues in modern nanoelectronics. The quality of contact can be improved by nonlocal laser annealing at increased power. The improvement of thermal contacts to initially rough metal electrodes is attributed to local melting of the metal surface under laser heating, and increased area of real metal-graphene contact. The accuracy of thermal conductivity measurements for suspended multilayer graphene (MLG) akes by micro-Raman technique was shown to depend critically on the quality of thermal contacts between the akes and metal electrodes used as a heat sink. Improvement of the thermal contacts was observed also between MLG and silicon oxide surface, with more efcient heat transfer from graphene as compared with the graphene-metal case.
