UHV system for spectroscopy with metastable probe atoms and thermal desorption spectroscopy

在项目框架内，将采购并投入使用亚稳探针原子真空光谱仪和热解吸光谱仪，从而弥补现有方法上的空白。亚稳探针原子的光谱学具有极高的表面灵敏度，并且与光电发射相结合，已被证明是一种非常有效的方法，特别是在低覆盖率范围内各种表面上分子吸附的研究中。从热脱附过程中可以得到吸附物的种类、数量、脱附能和脱附顺序等重要信息。两种方法相辅相成，是一种理想的方法，丰富了现有的方法。所要求的设备应该对当前的研究主题做出重要贡献。这包括氮化物和氧化物表面（特别是III族氮化物和氧化铟以及氧化锌）和吸附剂的研究，光电化学水分解的研究，以及离子液体的研究

Within the framework of the project, a vacuum apparatus for spectroscopy with metastable probe atoms and thermal desorption spectroscopy will be procured and put into operation, thus closing existing methodological gaps. The spectroscopy with metastable probe atoms is characterized by an extremely high surface sensitivity and - in combination with the photoemission - has proven to be a very powerful method, especially in the investigation of molecular adsorbates on various surfaces in the range of low coverages.From the thermal desorption important information on the type and amount of adsorbates and their desorption energy and order can be obtained. Both methods complement each other in an ideal way and enrich the currently available methods. The requested device should provide an essential contribution to current research topics. This includes the investigation of nitride and oxide surfaces (especially group III nitrides and indium oxide as well as zinc oxide) and adsorbates, investigations of photoelectrochemical water splitting, as well as work on ionic liquids
