Abstract

Single and few-layer graphene sheets with sizes up to 100 micron were synthesized using physico-chemical method by dispersing highly ordered pyrolytic graphite (HOPG) flakes into N, N-dimethylformamide (DMF) solution. The layer structure and thickness of graphene sheets were characterized with transmission electron microscopy (TEM), scanning electron microscopy (SEM), atomic force microscopy (AFM) and Raman spectroscopy. Synthesized graphene sheets were transferred to solid substrates for further processing. Field-effect transistor with individual graphene sheet was fabricated. In ambient conditions, graphene sheets were found to exhibit p-type behavior.
