Using a graphene nanoribbon suspended over a trench, a team of researchers at the University of Science and Technology of China has discovered a link between the nanomechanical motion and conductance through a single-electron transistor (SET). This nano-electromechanical system (NEMS) exploits a gold gating contact in the bottom of the trench that is used to […]
