Crystalline material is popular, few sites in this regard. Yue Crystal Materials Co., Ltd. Shandong days, even if there is not very professional, very easy to exchange, please recommend a few highly specialized crystalline materials site, I know There are the following, there are home on a presentation, as follows: China crystal material is related to the crystal mesh material professional integrated international portal of several crystals by senior industry experts co-founded, the specific contents include: nonlinear optical crystal, laser crystal infrared crystals, piezoelectric crystals, crystal La Man Laman displacement, scintillation crystal, pyroelectric crystals, electro-optical crystal, crystal terahertz, THz crystals, semiconductor crystals, crystal composite function, since doubling crystal, optical superlattice crystals , doubling crystal, organic crystals, soft crystals, biological crystals, metal single crystal thin film crystals, quartz, semi-metallic organic nonlinear optical crystal, etc., in order to effectively "promote the development of crystalline materials industry, active academic atmosphere crystal industry." China's network to break the traditional crystalline materials Construction Model academic sites and industry sites, in addition to building a professional outside the silicon carbide crystal materials industry database, but also for building the industry group, the Friends of crystal micro-Bo, Help Forum, Jobs and other interactive strong columns, favored by the majority of workers in crystalline materials. Joints refers to the actual interface between the single crystal twinning mutual engagement. Twinning to joints for the sector, both sides are not mutually continuous single crystal lattice. Stepped joints can be quite irregular or semi-insulating silicon carbide, also for a plane, and is equivalent to two single crystals in a public face each other. Joints often in parallel with a simple index single crystal in the crystal surface, then you can use the symbol of the crystal surface, said joining direction. However, individual twinning, the joints may also be unreasonable for an index faces. Joining a single crystal can be parallel to the plane of symmetry, but in fact it is often coincident with the twin planes, or parallel to the twin crystal axis. Twinning law refers to the double-crystal single crystal interconnected among law students. Twinning law is characterized by a double-crystal elements, and has often been given a specific name. Its nomenclature is as follows: a recurrent feature of the double-crystal mineral named after. Such as spinel group minerals to (111) twin plane, said spinel law; to the initial discovery of the double crystal place names, such as feldspar to C axis, namely (001) double crystal zone axis Carlsbad Law twin crystal axis; twin crystal shape named group minerals such as rutile to (101) for the twin planes geniculate twinning law (also known as the elbow-shaped double-crystal); and engaging with the twin plane face names, such as calcite crystal plane to (012) negative rhombohedron of twin planes and joints of twinning is called negative rhombohedral twinning law.
