Knowledge of braided mesh tube-films Crystal structure—crystal form of crystallites in the film Amorphous structure—disordered structure, short-range order, remote disorder. Amorphous structures - extremely small <2 nm grains and randomly arranged. High melting point metal film, high melting point non-metallic compound film, certain compound film of carbon silicon germanium, and co-precipitation film of two incompatible materials.
Polycrystalline structure - randomly oriented crystallite composition, grain 10-100 nm low melting point metal film. Welcome to the company's official website http://
Fiber structure - a film with preferred orientation of the grains.
Single fiber structure - each crystallite is preferentially oriented in only one direction.
Double fiber structure - each crystallite is preferentially oriented in both directions. Various piezoelectric microcrystalline films. Weaving the network tube The appearance of the fiber structure can be in the nucleation stage, the growth stage, or in the annealing process.
Single crystal structures - mostly formed in epitaxy. Epitaxial film, various semiconductor epitaxial films. Under certain conditions, the microstructure of the film may change, such as from disorder to polymorphism. The performance of the film changes significantly with the change of the organizational structure.
In most cases, the crystal structure of the crystallites in the film is the same as that of the bulk, except that the grain orientation and grain size may be different from the bulk.
Lattice mismatch: The lattice constant of the film material does not match the substrate. There is a large internal stress and surface tension in the braided web film.
At the interface, the crystal lattice is distorted to facilitate mating with the substrate.
