Transparent Conductive Oxides: Applications and Properties

This lecture covers the applications and properties of Transparent Conductive Oxides (TCOs), which are materials that can transmit light and conduct electricity simultaneously. The instructor discusses their use as transparent electrodes in optoelectronic devices, such as touch screens, TFTs, OLEDs, and solar cells. Key topics include the high electrical conductivity and optical transmittance required for these applications, as well as the importance of low surface roughness and uniformity. The lecture also explores the basic properties of TCOs, including their semiconductor nature and the influence of free carriers on their infrared properties.
