ZnO Deposition and Application
|
ZnO has a bandgap of 3.37eV and binding energy of 60eV, hence it can be used in applications that uses ultraviolet lasers, semiconductors and optoelectronic applications. In addition, ZnO have high refractive index, high thermal conductivity, antibacterial and UV protective properties hence, it is usually used to coat or added to the several materials and products, including plastics, ceramics, glass, cement, rubber, lubricants, paints, ointments, adhesives, sealants, concrete manufacture, pigments, food, batteries, ferrites, fire-retardant agents, etc.
Pulsed-Layer Deposition (PLD), Atomic Layer Deposition (ALD), and Sputtering (Sputter) techniques are the common techniques that are used to coat materials with thin layer of ZnO with high purity and uniformity. Opto-electronics parts, solar cells, semiconductor materials are the usual materials being coated with ZnO. AdNaNoTek UHV Deposition Systems provide ultra-high vacuum environment to reduce contamination; provides good pulse laser to enhance process stability; and simple and reliable user interface to ensure reproducibility and high production rate.
