Abstract
The invention relates to a growth unit for continuous growth of two-dimensional atomic crystal materials. The growth unit comprises a cylindrical thermal insulation layer, and a bearing surface arranged inside the tubular thermal insulation layer for supporting a growth substrate is arranged on the bearing surface. The heating component is electrically insulated from the bearing surface; the growth substrate moves from one end surface of the cylindrical thermal insulation layer to the other end surface under the bearing action of the bearing surface. The invention provides a growth unit for continuous growth of two-dimensional atomic crystal materials, which provides an environment for the growth of two-dimensional atomic crystal materials; a plurality of the growth units can be connected, and the cylindrical shape of each growth unit can be kept warm The layers are seamlessly connected to obtain a growth system for continuously growing two-dimensional atomic crystal materials, and the temperature controllability of the two-dimensional atomic crystal material growth process is realized.
Description
technical field [0001] The invention relates to the technical field of growth of two-dimensional atomic crystal materials, in particular to a growth unit, system and equipment for continuously growing two-dimensional atomic crystal materials. Background technique [0002] A two-dimensional atomic crystal refers to a two-dimensional material with a thickness of only one or several atoms. In essence, it is more like a huge two-dimensional molecule. Because of its absolute two-dimensional structure, this material has amazing Unexpected features and functions. Typical two-dimensional atomic crystal materials include graphene materials and boron nitride materials. Graphene is a two-dimensional material with a hexagonal honeycomb lattice composed of carbon atoms with sp2 hybrid orbitals, and only one carbon atom thick; hexagonal boron nitride (BN) and graphite are isoelectronic Body, known as white graphite, has a layered structure similar to graphite, has good lubricity, electr...
