Abstract

Nanoscale channel formation and characterization in ultrathin graphite film are performed. Two narrow channels with a submicron square connected in series are patterned by electron-beam lithography followed by oxygen plasma etching. The patterned film showed Coulomb blockade oscillations in the source-drain current upon a gate voltage change at 4.2 K. The Coulomb blockade effect occurred due to the electric potential modulation in the narrow graphite channels.
