Semiconductor materials of zinc sulfide

Zinc sulfide is a sulfur and zinc semiconductor material in the II-VI group compound. The molecular formula is ZnS; the molecular weight is 97.45, melting point is 1020 ℃ (15MPa); in white crystal, the lattice constant is 0.547nm; in hexagonal crystal form, the density is 4.08g/cm3. Almost insoluble in water but soluble in acids. Long-term exposure to humid air can convert it into zinc sulfate. The band gap is 3.6eV, the widest among the Ⅱ - Ⅵ compound semiconductor materials. Therefore, blue light-emitting tubes can be made. Powdered zinc sulfide is the most crucial field luminescent and photoluminescent material for preparing fluorescent screens and scoreboard displays for picture tubes. It is also a window and coating material in infrared chemical book materials. The zinc sulfide used in fluorescent powder is mainly prepared by the solution method, characterized by high yield and low cost. The high-purity zinc sulfide synthesized by direct vapor phase synthesis of elements forms needle-like crystals used to prepare high-performance coating materials and single-crystal raw materials. Zinc sulfide single crystals can be grown using a high-pressure single-crystal furnace and chemical vapor transport (CVD) method. Zinc sulfide sheets for optical materials can be prepared using hot pressing and CVD methods, which are widely used in window materials of lasers. Recently, the organometallic chemical vapor deposition method has been used primarily to prepare zinc sulfide film materials. Due to low growth temperature, the generated film has good integrity and few defects, and it is easy to prepare heterojunction optoelectronic devices.
