▎ 摘  要

NOVELTY - The device has a silicon substrate (4) fixed at a groove in the silicon substrate. A gate (3) fixed at the bottom of the groove. A source/drain electrode (2) is contact at two ends of a groove top part, and a suspended graphene (1) is located above the source and drain electrode contact. The suspended graphene is provided with two end straight sections fixed on the source or drain electrode. A middle suspension section is suspended above the groove. An optical resonant cavity is formed between the intermediate suspension section of the suspended graphene and the silicone substrate. A driving laser and a detecting laser are irradiated between the middle suspension sections. A direct current voltage is applied to the gate to generate an electric field. The suspension graphene generates certain power of jute heat, and adjusts size of juele heat power to realize dynamic control of the vibrator. USE - Device for controlling graphene mechanical vibrator non-linear by using joule heat in micro-nano electromechanical system and basic scientific research. ADVANTAGE - The graphene mechanical vibrator has simple technique, small volume, high resonance frequency, and realizes the dynamic regulation of the non-linear of Joule heat. The device has easy preparation, convenient control, low cost, short preparation period, and has important meaning and research value in the field of high temperature. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for controlling graphene mechanical vibrator non-linear by using joule heat. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a device for controlling graphene mechanical vibrator non-linear by using joule heat in micro-nano electromechanical system and basic scientific research. 1Suspended graphene 2Source/drain electrode 3Gate 4Silicon substrate
