▎ 摘　　要

NOVELTY - The detector has an emitting electrode (1) and a collecting electrode (8) electrically connected with a graphene substrate (2). A light-type semi-transparent semi-reflecting mirror (4) divides a carrier emitted by the emitting electrode after passing through a light-type momentum selector (3). A grid of the light-type semi-transparent semi-reflecting mirror and a light-type full reflector (5) are respectively arranged on a vertical upper part of the graphene substrate and the light-type momentum selector. An insulating layer (9) is arranged between the grid of the light-type semi-transparent semi-reflecting mirror and the graphene substrate. The graphene substrate is arranged with a substrate electrode (10). USE - Photo-Michelson interferometer molecular detector. ADVANTAGE - The detector can ensure short wavelength of graphene light transport, realize potential changing sensitive, so that provides large collected electronic current change when a photoelectron detection arm is absorbed with molecules, obtain size and range of molecular and graphene to measure the molecule, effectively reflect light-type particles to the collecting electrode by forming the carrier through the light-type full reflector, ensure high reflectivity by using rapid gate adjusting according to voltage between the graphene substrate and the substrate electrode and effectively collect scattered electrons to the collection electrode by a photo negative refractive lens so as to reduce influence of carrier scattering.
