We report in CPEM 2012 the preparation of the micromechanical cleavage (MC) and the chemical vapor deposition (CVD) graphene films and the fabrication of the quantum Hall resistance (QHR) devices on these films. Graphene films are on the SiO2/Si substrates. Spectroscopic Raman analysis indicates monolayer graphene films are obtained. Hall bar structures are formed on graphene films by e-beam lithography,...
A novel low-stress process for transferring thermal CVD single-layer graphene from copper foils to destination substrates is demonstrated. Electrical and optical characteristics of as-transferred graphene and the hydrogen remote-plasma modified graphene are presented. Although graphene is mechanically very strong considering its atomically thin structure, large-area single-layer graphene is practically...
