O 96: Focus Session: Surface Transport at the Atomic Scale
Freitag, 5. April 2019, 10:30–13:00, H15
The ability to probe electronic transport on nano- and even atomic scaled structures opened a new field. Besides break junction techniques for realizing 2-terminal transport setups, recently, also multiprobe technique based on scanning tunneling microcopy (STM) allowed to go beyond and demonstrated its capability to reveal fundamental charge transport properties. This Focus Session will give an brief overview over the progress made on various topics with surface transport, ranging from functionalized semiconductor surfaces, 2D materials, topological insulators, helical molecules down to atomic wires.
Organizers: Christoph Tegenkamp (TU Chemnitz) and Bert Voigtländer (FZ Jülich).
