Nominator's project description
| The scientific interests of Prof. Dr. F. J. Himpsel are in surface science and nano-science. Utilizing his experience with synchrotron radiation he devised methods for mapping energy bands of solids and surfaces by angle-resolved photoemission. As complement he developed inverse photoemission for the study of unoccupied states. These two complementary experimental techniques are combined in two-photon photoemission which was first used successfully by Professor Himpsel to study image-potential states. He further used surface-sensitive core-level spectroscopy for identifying chemical species at semiconductor surfaces and interfaces. Currently, he is working on self-assembled nanostructures at surfaces, such as magnetic quantum wells, atom chains, and an atomic scale memory. During his stay in Germany Professor Himpsel plans to study the electronic properties of atomic wires with two-photon photoemission. |
