论文摘要
在基于激光的高重复速率极端紫外线（EUV）的光源和多维光电子光谱的最新进展使新一代时间分辨的光发射实验可以建立。在这里，我们提出了一个设置，该设置是由1 MHz飞秒EUV台式光源驱动的时间分辨动量显微镜，该设置优化了26.5 eV光子的生成。该设置可同时访问光电子动能和平面动量的时间演变。我们根据一系列对石墨烯的静态和时间分辨的测量来讨论新实验的机会和局限性。
Recent progress in laser-based high-repetition rate extreme ultraviolet (EUV) lightsources and multidimensional photoelectron spectroscopy enable the build-up of a new generation of time-resolved photoemission experiments. Here, we present a setup for time-resolved momentum microscopy driven by a 1 MHz femtosecond EUV table-top light source optimized for the generation of 26.5 eV photons. The setup provides simultaneous access to the temporal evolution of the photoelectron's kinetic energy and in-plane momentum. We discuss opportunities and limitations of our new experiment based on a series of static and time-resolved measurements on graphene.
