  Traditionally, Schottky diodes are used statically in the electronic
information industry but dynamic state Schottky diodes based applications have
been rarely explored. Herein, a novel Schottky diode named moving Schottky
diode generator has been designed, which can convert mechanical energy into
electrical energy with voltage output as high as 0.6V, by means of lateral
movement between graphene/metal film and semiconductor, where the semiconductor
can be non-piezoelectric materials. The mechanism is based on the built-in
electric field separation of drifting electrons in moving van der Waals
Schottky diode. The power output can be further increased in future through
optimizing the Schottky diode. The graphene film/silicon moving van der Waals
Schottky diode based generator behaves better stability. This direct-current
generator has the potential of converting mechanical efficiently and
vibrational energy into electricity and enables many promising applications.
