▎ 摘　　要

NOVELTY - The device includes a control layer (1), an intermediate medium layer (2), and a base layer (3). The control layer, the intermediate medium layer, and the base layer are stacked from top to bottom. The control layer is a graphene layer. The intermediate dielectric layer is a polymethyl methacrylate layer. The base layer is a silicon layer. The graphene layer is provided with a thickness of 1 nm, the intermediate dielectric layer is provided with a thickness of 50 nm, and the base layer is provided with a thickness of 200 nm. USE - Dynamic-adjustable communication function device. ADVANTAGE - The inconvenience of processing and manufacturing is avoided. The integration and miniaturization of communication function devices is achieved. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the Y-shaped dynamically adjustable communication function device. Control layer (1) Intermediate medium layer (2) Base layer (3)
