Tin Oxide SnO2 PLD Target

Introduction to the properties of SnO2 thin films for optoelectronics

SnO2, also known as tin dioxide, is a wide-gap semiconductor with interesting optoelectronic properties. It has been used as a material for various thin film applications in fields such as solar cells, gas sensors, and transparent conductive films.

Optical and Electronic Properties of SnO2

SnO2 has a high transparency in the visible light range and a high electron mobility. These properties make it a promising material for use in optoelectronics applications, such as transparent electrodes in solar cells or touch screens.

Optoelectric Properties of SnO2 Compared to In2O3

SnO2 has comparable optoelectric properties to another well-known material, Indium Tin Oxide (In2O3). Both materials have high transparency and electron mobility, making them useful in optoelectronics. However, SnO2 has the advantage of being more abundant and less expensive than In2O3, making it a potentially more attractive material for commercial applications.

Crystal Structure of SnO2

SnO2 has a tetragonal crystal structure with tetragonal rutile structure. 

Typical Substrates for Epitaxial Growth of SnO2

Good lattice matching between the substrate and SnO2 is important for high-quality epitaxial growth of SnO2 thin films. Some typical substrates used for SnO2 growth include sapphire, rutile TiO2, and silicon dioxide (SiO2).
