Photoemission studies of Fermi surfaces, of wide bandgap semi-conductors and quasi crystals

费米表面、宽禁带半导体和准晶体的光电发射研究。了解导电材料费米表面的详细形状对于理解其电学和磁学性质是至关重要的。我们将使用角分辨光发射结合同步辐射来探索技术上重要的磁性合金的费米表面，驱动层状化合物中电荷密度波发生的机制以及宽带隙半导体（如GaN， SiC和选定的准晶体）的电子特性。这些测量将使用目前正在拉筹伯大学建造的独特的高分辨率环形光谱仪进行。

Photoemission studies of Fermi surfaces, of wide bandgap semi-conductors and quasi crystals. Knowledge of the detailed shape of the Fermi surface of a conducting material is vital for an understanding of its electrical and magnetic properties. We will use angle resolved photo-emission in conjunction with synchrotron radiation to explore the Fermi surfaces of technologically important magnetic alloys, the mechanism driving the occurance of charge density waaves in layer compounds and the electronic properties of wide band-gap semi-conductors such as GaN, SiC and of selected quasi crystals. These measurements will be performed using a unique high resolution toroidal spectrometer currently under construction at La Trobe university.
