在同步加速器 BESSY II 的 PM4 软 X 射线偶极子束线上实施具有 1.25 MHz 脉冲选择器的高透射率角分辨右时间电子能谱仪，创造了通过光电子能谱以最小辐射剂量查询电子结构的独特功能。固态样品可以使用标准 UHV 技术进行制备和表征，并快速从各个制备室转移到 4 轴温控测量台。同步 MHz 激光系统能够从皮秒时间尺度开始进行激发态表征和动力学研究。本文介绍了 PM4 光束线和 LowDosePES 终端站的主要特性。石墨烯、一种用于太阳能电池的有机空穴传输材料和过渡金属二硫属化物 MoS2 的最新结果展示了仪器性能。 (C) 2017 年作者。由 Elsevier B.V. 出版
The implementation of a high-transmission, angular-resolved time-of-Right electron spectrometer with a 1.25 MHz pulse selector at the PM4 soft X-ray dipole beamline of the synchrotron BESSY II creates unique capabilities to inquire electronic structure via photoelectron spectroscopy with a minimum of radiation dose. Solid-state samples can be prepared and characterized with standard UHV techniques and rapidly transferred from various preparation chambers to a 4-axis temperature-controlled measurement stage. A synchronized MHz laser system enables excited-state characterization and dynamical studies starting from the picosecond timescale. This article introduces the principal characteristics of the PM4 beamline and LowDosePES end-station. Recent results from graphene, an organic hole transport material for solar cells and the transition metal dichalcogenide MoS2 are presented to demonstrate the instrument performances.
