Abstract

The invention discloses a nanoscale PN junction diode rectifier based on an MnBi2Te4 single layer, and belongs to the technical field of nanoscale electronic devices. Key points of the technical scheme of the invention are as follows: the nanoscale PN junction diode rectifier based on the MnBi2Te4 single layer is composed of a single-layer structure of a MnBi2Te4 material, p-type doping is carriedout at one end of a single-layer structure of the MnBi2Te4 material, N-type doping is carried out at the other end, and a PN junction structure is formed; a drain electrode and a source electrode areapplied to the two ends of the PN junction structure respectively, and the PN junction structure is placed on a substrate such as silicon dioxide to form a diode structure; when forward bias voltageand reverse bias voltage are applied to the two ends of the diode structure respectively, the diode structure shows the rectification characteristic. The rectifier disclosed in the invention has the advantages of being ultrathin in structure, adjustable in size, remarkable in rectification effect and the like.

Description

Technical field [0001] The invention belongs to the technical field of nanoscale electronic devices, and specifically relates to a MnBi-based 2 Te 4 Single-layer nano-scale PN junction diode rectifier. Background technique [0002] In the post-Moore era, the development of silicon-based devices has encountered a major bottleneck, and it is necessary to find new materials to replace traditional silicon-based devices. Two-dimensional materials may become potential candidate materials for devices due to their unique properties in the fields of electricity and other fields. [0003] In recent years, two-dimensional monolayer materials have aroused great research interest of researchers in many fields due to their unique geometric and electronic structure, mechanical and optoelectronic properties. Such as graphene, silylene, germanene, boron nitride, transition metal disulfide, MX ene, phosphorene, tinene, boronene, etc. have been successfully prepared. A large number of studies have ...
