ZnO is a promising semiconductor for optoelectronic devices namely green, blue, ultraviolet (UV) and white light emitting diodes (LEDs) and ultimately UV lasers. It can also act as a transparent conductive oxide which has applications in flat panel displays and photovoltaic devices. Because of these potential applications, ZnO is the 'hottest' semiconductor with abounding literature and four new international conferences organised on progress in this research area in recent years. This project is an excellent opportunity for Australia to increase its strength in optoelectronic device research and to provide an understanding of some fundamental issues in doping, defect formation, diffusion and annihilation in ZnO.Read moreRead less

Improving silicon grain boundaries by linking electronic material quality and device manufacturing conditions. This project develops our recent findings for improving silicon grain boundaries in electronic devices such as cheap solar cells, active matrix displays, thin-film transistors, etc. The performance of such devices and their applications have been limited mainly because no simple link between manufacturing conditions and device quality has been found. However, we recently verified a phys ....Improving silicon grain boundaries by linking electronic material quality and device manufacturing conditions. This project develops our recent findings for improving silicon grain boundaries in electronic devices such as cheap solar cells, active matrix displays, thin-film transistors, etc. The performance of such devices and their applications have been limited mainly because no simple link between manufacturing conditions and device quality has been found. However, we recently verified a physical model description of grain boundaries on a broad range of devices, and this allows us to find such a link and to address prevailing problems from a new perspective. This will improve both the understanding and the manufacturing of such devices.Read moreRead less
