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

在该项目的框架内，将采购一台用于亚稳态探测原子光谱分析和热解吸光谱分析的真空装置并投入使用，从而缩小现有的方法学空白。亚稳态探测原子光谱具有极高的表面灵敏度，与光电子能谱相结合，已被证明是一种非常有效的方法，特别是在研究分子在低覆盖度范围内的各种表面上的吸附时。从热脱附可以获得关于吸附的类型和数量以及它们的脱附能和顺序的重要信息。这两种方法在理想的情况下相辅相成，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(特别是第三类氮化物和氧化铟以及氧化锌)和吸附物的研究，光电化学水分解的研究，以及关于离子液体的工作。
