1. Single crystal silicon wafer has a diamond lattice, the crystal is hard and brittle, has a metallic luster, and can conduct electricity, but its conductivity is lower than that of metal, and it increases with temperature, which has semiconductor properties. Monocrystalline silicon wafers are important semiconductor materials. Doping a small amount of group IIIA elements into single crystal silicon forms a P-type semiconductor, and doping a small amount of group VA elements forms an N-type semiconductor. The combination of N-type and P-type semiconductors can make a solar cell. Radiation energy is converted into electrical energy.
2. Monocrystalline silicon wafers are raw materials for manufacturing semiconductor silicon devices, and are used to make high-power rectifiers, high-power transistors, diodes, switching devices, etc. It is a promising material in the development of energy.
3. According to different crystal growth methods, single crystal silicon wafers are divided into Czochralski method (CZ), zone melting method (FZ) and epitaxy method. Single crystal silicon rods are grown by Czochralski method and zone melting method, and single crystal silicon thin films are grown by epitaxial method. Single crystal silicon wafers grown by the Czochralski method are mainly used in semiconductor integrated circuits, diodes, epitaxial wafer substrates, and solar cells.
