▎ 摘  要

NOVELTY - The device has a graphene covering layer (106), a molybdenum oxide thin layer (102) and a substrate layer which are sequentially arranged from top to bottom. A metal antenna (103) is arranged on the graphene covering layer. A geometric dimension of the metal antenna is 10 nm-30 um, and a thickness is 20 nm-5 um. A geometric dimension of the molybdenum oxide thin layer is 1 um-50um, and a thickness is 10 nm-1 um. The graphene covering layer is realized by fermi level variation, and the fermi level variation is controlled by chemical doping and electrical gate voltage. The substrate layer comprises a silicon dioxide substrate and a gold substrate (101) which are sequentially arranged. The molybdenum oxide thin layer is arranged on an upper portion of the gold substrate. USE - Graphene molybdenum oxide heterojunction polarization excimer wavefront control device for transmission of in-plane wave for optical imaging, photon integration and quantum optics. Can also be used for researching mutual coupling of different polarized excimer modes. ADVANTAGE - The dynamic regulation and control of the wavefront shape of a hyperbolic phonon polarization excimer and plasmon hybridization mode excited in a heterostructure and topological transformation are realized. The wavefront shape of the graphene molybdenum oxide heterojunction hybrid excimer is dynamically regulated and controlled by changing the carrier concentration. The control device is simple and easy to implement, and flexible and accurate. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing graphene molybdenum oxide heterojunction polarization excimer wavefront control device. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic diagram of the voltage-regulated graphene molybdenum oxide heterojunction device.
