摘要: Contamination of graphene due to residues from nanofabrication often introduces background doping and reduces electron mobility. For samples high electronic quality, post-lithography cleaning treatments are therefore needed. We report that mechanical based on contact mode atomic force microscopy removes significantly improves the properties. A mechanically cleaned dual-gated bilayer transistor with hexagonal boron nitride dielectrics exhibited a mobility ∼36 000 cm2/Vs at low temperature.
