Transparent oxide semiconductor thin film is a thin film with transparency, conductivity, and semiconductor properties, usually made of metal oxides such as zinc oxide, indium oxide, tin oxide, and other materials. These materials have excellent electrical and optical properties, and are therefore widely used in electronic and optoelectronic devices.
The preparation methods of transparent oxide semiconductor films include physical vapor deposition, chemical vapor deposition, sol gel method and other technologies. Among them, physical vapor deposition is one of the most commonly used preparation methods, which can deposit metal oxide materials on substrates through methods such as thermal evaporation or magnetron sputtering under high vacuum. Chemical vapor deposition utilizes chemical reactions in the gas phase to achieve material deposition. Sol gel method is to prepare materials through the synthesis of sol and gel, which has the advantages of low cost and easy to expand production.
Transparent oxide semiconductor thin filmThe applications include LCD displays, organic light-emitting diodes, solar cells, and other fields. In these applications, transparent oxide semiconductor thin films can be used as electrode materials, transport layer materials, reflective layer materials, etc.
Transparent oxide semiconductor (TCOs) thin films are also a type of optoelectronic device material with high transparency and conductivity. It has a wide range of applications in the field of optoelectronics. The following are the performance characteristics and application scope of transparent oxide semiconductor thin films:
● Transparency: TCOs film has a high transmittance, which can reach over 90%. It can effectively reflect sunlight under sunlight exposure, thereby improving the service life of the light source.
● Conductivity: TCOs thin films have high conductivity and can provide transport channels for electrons and holes, promoting their separation.
● Thermal stability: TCOs thin films have good thermal stability under both high and low temperature conditions, which can prevent signal attenuation caused by temperature changes.
● Antioxidant activity: TCOs thin films have high antioxidant properties, which can resist the damage caused by moisture and oxygen in the external environment and improve the reliability of the light source.
Color stability: The color of TCOs film does not change significantly after exposure to light and temperature changes, which is crucial for various light sources and applications.
Surface roughness: The surface of TCOs film is relatively rough and smooth, which helps to improve the contact fastness between the light source and the substrate and reduce signal attenuation.
The above are some performance characteristics and application ranges of transparent oxide semiconductor thin films. In addition, TCOs thin films can also be used in other fields, such as displays, touch screens, etc.
