High Frequency ZnO Thin Film Transistors

Thin film transistors (TFT) are the essential elements of flat panel display electronics. The current technology for this application based on amorphous or polycrystalline Si films has speed limitations due to low mobility of such films. As the demand for higher speed electronics increase with display size and complexity, alternative technologies are being developed based on heavy metal oxide compounds such as ZnO. The increased mobility offered by this technology together with its robustness to environmental conditions, make it a suitable candidate for future applications.
