Surface Science Laboratory
Chemical Engineering
Research Activity
Metal/semiconductor interfaces, organic electronics, organic/inorganic interfaces,
photeelectron spectroscopies, work function, surface characterisation, nanomaterials, biomaterials,
A large variety of surface characterization techniques (XPS/XAES, UPS, AES, LEISS, LEED, WF, TPD) are used for the determination of structure, composition and electronic properties of surfaces and interfaces (thin films). Both basic and applied research, as well as analytical services to third parties are conducted. The main research topics include : (a) Mono- and bi-metallic ultrathin films on oxides, (b) interfaces of metals, semiconductors or oxides with organic films, (c) metal/ SiC interfaces. There exists extensive experience in surface analysis of a broad range of both organic and inorganic materials.
