In a collaborative effort with the group of Prof. F. Reinert and Dr. H. Bentmann at University Würzburg the electronic structure of a tellurium (Te) adsorbate structure was investigated by angle resolved photoemission (ARPES, U Würzburg) and structure determination (U Erlangen). It turned out, that ...
When molecules adsorb on surfaces many interesting phenomena arise. One is the occurrence of chirality (handedness) from molecules that a achiral in the gas phase. These so called "prochiral" molecule can adsorb in two mirror symmetric ways on a surface and become chiral, since the two configuration...
The German Research Foundation (Deutsche Forschungsgemeinschaft, DFG) has awarded funding to the group for the investigation of the growth and structure of ultra-thin transition metal telluride films. Such films find applications as thermoelectrics, sensors, phase-change materials, etc. But more int...
Materials that appear in different structural phases are of great interest since they test our fundamental understanding of the properties of a substance. The wurtzite phase of cobalt(II) oxide is a rather elusive polymorph of CoO that normally has the simple rocksalt crystal structure. Up to now it...
Combining the expertise of all groups at the chair of solid state physics we unraveled the structural and electronic properties of CuTe chains grown on Cu(111).
These chains form after the deposition of one-third of a monolayer of Te and a subsequent annealing step. They are extremely well ordere...
By employing Scanning Tunneling Microscopy (STM) and Density Functional Theory (DFT) we investigated the behaviour of two different porphyrins on ultra thin cobalt oxide films grown on an iridium single crystal.
The two molecules depciced on the image differ in terms of their anchoring points to ...
Next week is the big week for Feifei and Sebastian. Both are going to defend their theses.
Sebastian Otto will take the lead on Thursday. He will defend his thesis about "Two-photon photoelectron spectroscopy on topological insulators" on Thursday 14:00, lecture hall F. The public ta...
Molecules cannot "decide" which partner they want to bind to. Therefore it is an enticing problem to understand how chemical reactions become selective, in our case stereoselective.
By carefully analyzing STM data and combining them with extensive DFT calculations we unraveled the reason why partic...
The second Edition of the textbook "Oberflächenphysik" (surface science) by Prof. Thomas Fauster, Dr. Lutz Hammer, Prof. Klaus Heinz, and Prof. M. Alexander Schneider is available from today on. The textbook gives a compact overview about surface science and its experimental methods. For now, the bo...
The structural analysis of TaS2 is published as editors' suggestion in PRB today. This record-breaking LEED-I(V) analysis includes 128 inequivalent beams of diffracted electrons to determine the positions of 78 atoms in the two outmost trilayers.
Fun fact: PRB announced it next to the Nobel Prize...
