Condensed matter: electronic structure

该项目旨在开发新型透明导电材料，用于玻璃上的光电应用。目前使用的氟掺杂二氧化锡正在接近其技术极限，需要新材料来保持薄膜光伏器件、节能玻璃、电子显示器和照明方面的效率和性能改进的步伐。由于强关联电子系统的等离子体频率较低，导致此类材料的反射边向较低能量移动，从而增强了在电磁光谱可见部分的透射率，因此是本研究的主要重点。学生将使用脉冲激光沉积(PLD)在单晶和玻璃衬底上制备高质量的新型透明导电材料薄膜，用于表征和性能测量。进一步的开发将采用其他适合在玻璃衬底上大规模生产的薄膜沉积方法，如化学气相沉积、磁控溅射、喷雾热解等，并将需要使用位于兰开夏郡Lathom的NSG集团技术中心的实验室。使用同步加速器X射线和中子散射设施的机会很多。

This project aims to develop new transparent conducting materials for optoelectronic applications on glass. Currently used fluorine doped tin oxide is approaching its technological limitations and new materials are required to maintain the pace of efficiency and performance improvements in thin film PV devices, energy saving glazing and electronic displays and lighting. Strongly correlated electron systems are the main focus in this research because of their low plasma frequencies, resulting in the reflection edge of such materials to be shifted to lower energies, therefore enhancing the transmission in the visible part of the electromagnetic spectrum.The student will use pulsed laser deposition (PLD) to prepare high quality films of new transparent conducting materials on single crystal and glass substrates for characterisation and property measurements. Further development will employ other thin film deposition methods suitable for large-scale production on glass substrates e.g. chemical vapour deposition, magnetron sputtering, spray pyrolysis etc. in collaboration with NSG Group and will require use of the laboratories at the NSG Group Technical Centre at Lathom, Lancashire. There are extensive opportunities to use synchrotron X-ray and neutron scattering facilities.
