Abstract

The invention relates to a vapor deposition device which comprises a reaction cavity (1), a reactant injection assembly, a vacuum pressure reduction assembly and a temperature control assembly. The reactant injection assembly and the vacuum pressure reduction assembly communicate with the reaction cavity (1). A substrate (2) is placed into the reaction cavity (1), after the reaction cavity (1) is vacuumized through the vacuum pressure reduction assembly, the vacuum pressure reduction assembly is closed, the reactant injection assembly is used for injecting a reactant into the reaction cavity (1), and the temperature control assembly controls temperature in the reaction cavity (1), so that the reactant is vaporized and deposited on the surface of the substrate (2). Compared with the prior art, the vapor deposition device has the beneficial effects of being convenient to operate, simple in structure, low in cost, suitable for large-scale commercialized application and the like, and the vapor deposition process is controllable.

Description

technical field [0001] The invention belongs to the field of material preparation and chemical synthesis, and in particular relates to a simple and low-cost vapor deposition device. Background technique [0002] With the rapid development of science and technology, the properties of materials and their preparation processes have become the key factors restricting the further development of the manufacturing industry. Composite materials have incomparable advantages over single materials and have become a new research hotspot in material science. The preparation methods of composite materials are various, which can be divided into gas phase method, liquid phase method and solid phase method according to the reaction form of substances. Compared with liquid-phase and solid-phase methods, gas-phase methods are widely used due to the advantages of mild reaction conditions, controllable reaction process, and uniform reaction products. [0003] Vapor deposition method is a gas-p...
