Project C01 aims to elucidate (a) the effect of ZnO surface hydration on the electronic structure and charge carrier dynamics and (b) evaluate doping strategies to steer the (proton-coupled) electron dynamics. The pro-ject utilizes scanning tunneling microscopy (STM) and spectroscopy (STS) combined with in-situ optical excita-tion to determine the impact of local defects and dopants on the electronic structure and site-specific PCET reactivity. Complementary time- and angle-resolved photoemission spectroscopy (trARPES) provides the opti-cally induced ultrafast charge transfer dynamics. C01 collaborates with C02/C03/C05 (sample preparation and exchange) and A01 (sum frequency generation spectroscopy).

项目C 01旨在阐明（a）ZnO表面水合对电子结构和电荷载流子动力学的影响，以及（B）评估掺杂策略以控制（质子耦合）电子动力学。该项目利用扫描隧道显微镜（STM）和光谱（STS）结合原位光激发，以确定局部缺陷和掺杂剂对电子结构和特定位置的PCET反应性的影响。互补时间和角度分辨光电子能谱（transARPES）提供了光诱导超快电荷转移动力学。C 01与C 02/C 03/C 05（样品制备和交换）和A01（和频发生光谱学）合作。
