▎ 摘　　要

NOVELTY - The structure has a graphene (G) layer arranged on a black phosphorus (BP) layer, where a magnetoresistance ratio of the graphene-black phosphorus hybrid structure is determined by a difference in a charge mobility and carrier density between the graphene layer and the black phosphorus layer, and charge mobility and/or the carrier density of the graphene layer is tunable by a gate voltage applied to the graphene-black phosphorus hybrid structure, and the graphene layer is monolayer graphene, and thickness of the black phosphorus layer is measured about 5-10 nanometer. USE - Graphene-black phosphorus hybrid structure for use in a magnetoresistance sensor (claimed). ADVANTAGE - The structure utilizes a Hall sensor that provides reasonable resolution in moderate and high magnetic fields with low cost and high temperature coefficient of resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a magnetoresistance sensor. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a layer of graphene and black phosphorus comprised in a graphene-black phosphorus hybrid structure.
