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

在项目的框架内，将采购带有亚稳定原子和热解吸光谱的光谱的真空设备并进行运行，从而缩小现有的方法论差距。具有亚稳态探针原子的光谱法的特征是表面敏感性极高，并且与光发射结合使用 - 已被证明是一种非常有力的方法，尤其是在研究各种表面上的分子吸附剂的研究中，在低覆盖范围内的各种表面。从低覆盖率范围内。从热吸收范围内，就可以及其deSorbates和dessorpers and deSorpers and Orderption and Orderptign and Orderption and Ordeptign and Orderption和Order量。两种方法都以理想的方式相互补充，并丰富当前可用的方法。请求的设备应为当前的研究主题提供基本贡献。这包括研究氮化物和氧化物表面（尤其是III组氮和氧化物以及氧化锌）和吸附物，光电化学水分裂的研究以及对离子液体的工作
