The project focuses on the determination of the electronic structure of organic charge-transfer salts by applying a novel approach of angle-resolved photoemission, called time-of-flight momentum microscopy. This gives access to the valence band structure and its temperature dependence, simultaneously in the relevant energy band and the full Brillouin zone with minimum radiation damage and high spatial resolution. Results for k-(BEDT-TTF)2X and TMTTF2X crystals will be compared with theoretical calculations. Synchrotron-based NEXAFS and HAXPES yield complementary information on details of the charge-transfer process.

该项目的重点是通过应用一种称为飞行时间动量显微镜的角分辨光电发射新方法来确定有机电荷转移盐的电子结构。这提供了访问的价带结构和它的温度依赖性，同时在相关的能带和整个布里渊区具有最小的辐射损伤和高空间分辨率。将k-（BEDT-TTF）2X和TMTTF 2X晶体的结果与理论计算进行比较。基于同步加速器的NEXAFS和HAXPES产生的电荷转移过程的细节互补的信息。
