Abstract

The present invention relates to a black phosphorene film memory and a preparation method thereof. The preparation method of the black phosphorene film memory comprises the following steps: (1) cleaning a substrate; (2) forming a bottom electrode on the substrate; (3) forming the black phosphorene film layer on the bottom electrode; (4) forming the graph of a top electrode on the black phosphorene film layer through a composition process; (5) forming the top electrode on the black phosphorene film layer, and obtaining a memory unit; (6) forming the graph of a cladding layer at the upper side of the memory unit through the composition process; and (7) finally forming the cladding layer to allow the cladding layer to coat the part of the black phosphorene film layer without being coated with the top electrode, and obtaining the memory. The black phosphorene film memory is rapid in the transforming speed and stable in read-write voltage.

Description

Technical field [0001] The invention belongs to the technical field of memory, and particularly relates to a black phosphorene film memory and a preparation method thereof. Background technique [0002] According to the International Semiconductor Technology Roadmap (ITRS) forecasts on the development trend of the integrated circuit field, by 2020, the feature size of integrated circuits will be reduced to less than 10 nanometers, so that traditional devices will face a series of technical and physical limits. challenge. At this time, new materials need to be introduced to solve many problems that traditional devices cannot solve. Two-dimensional crystals are nanometer-thick planar crystals stacked by several monoatomic layers. They have unique electrical, optical, and magnetic properties, and have their own unique structural advantages. Therefore, common two-dimensional materials such as graphene, Silylene, molybdenum disulfide and black phosphorene have all received extensive...
