Literature:

Spintronic devices based on ferromagnetic semiconductors, such as non-volatile magnetic memory, have the advantages of low power consumption, fast operation speed, high storage density and strong data retention, and are expected to integrate storage and computing, and have broad application prospects in future information technology and quantum computing fields. Two-dimensional magnetic semiconductor materials are essential to improve the performance of spintronic devices. However, most two-dimensional materials, including graphene, do not have intrinsic ferromagnetism and need to introduce magnetic properties by doping modification and other methods. Therefore, the search for new two-dimensional magnetic semiconductors with high Curie temperature will provide an important basis for the research of spintronic devices. Professor Sun Zhimei's team of Beihang University has made progress in the research of two-dimensional magnetic semiconductor materials, mainly including the following two aspects. (1) Through first-principles calculation and first-principles molecular dynamics simulation, we propose a new way to obtain two-dimensional intrinsic ferromagnetic semiconductors, that is, to obtain single-layer ferromagnetic semiconductors by stripping off anti-ferromagnetic van der Waals semiconductors; And we predict a new class of 2D intrinsic ferromagnetic semiconductors, monolayer CrOCl and CrOBr materials, whose Curie temperatures are much higher than those of 2D CrI3 and Cr2Ge2Te6 reported in the literature. The results show that this series of 2D materials can be obtained by mechanical stripping method similar to the preparation of graphene, and have good kinetic and thermodynamic stability. This work provides a new idea for the development of new 2D intrinsic ferromagnets, and the predicted 2D ferromagnetic CrOCl and CrOBr materials are expected to be applied to future spintronic devices. (2) Prediction of semi-metallic ferromagnetic two-dimensional Cr2C crystals and metal-insulator phase transitions induced by surface functionalization. Based on hybrid functional density theory, we predict the first semi-metallic ferromagnet material in the MXene family with tunable electronic properties and magnetism, whose charge transport is completely dominated by spin-up electrons, i.e. the flow of electrons through Cr2C will be 100% spin-polarized. The semi-metallic band gap of Cr2C is up to 2.85 eV, which guarantees that the 100% spin filtering property can be applied over a large bias range. When the surface of Cr2C is saturated with F, OH, H or Cl atomic groups, Cr2C will undergo a transition from metal to insulator, accompanied by a ferromagnetic to antiferromagnetic transition. Therefore, the energy gap width of the antiferromagnetic state can be well controlled by controlling the types of functionalized atomic groups on the surface.

Product introduction:

MAX phase ceramics (including titanium silicon carbide, Ti3AlC2 material, etc.) is a new type of attention can be processed conductive ceramic materials. This type of ceramics contains more than sixty terene carbides or nitrides. M represents the front metal element of the transition group; A represents the main group elements, mainly the elements of the third and fourth main groups; And X for the elements carbon or nitrogen. Ti3SiC2 is the most widely studied of these. Ti3SiC2 was successfully synthesized by hot pressing method in 1996 by Professor Barsoum M's research group of Drexel University in the United States, and its excellent performance was found. Due to the unique nano-layered crystal structure, this kind of ceramic material has the properties of anti-oxidation, self-lubrication, high fracture toughness at room temperature and conductive. This kind of material can be widely used as high temperature structural materials, electrode brush materials, chemical anti-corrosion materials and high temperature heating bodies. The products are mainly used in high temperature coatings, MXene precursors, conductive self-lubricating ceramics, lithium-ion batteries, supercapacitors, electrochemical catalysis.

Application Fields:

MAX has been widely used in nano-adsorption, biosensor, ion screening, catalysis, lithium-ion batteries, supercapacitors, lubrication and many other fields.
