"MBE-STM: from quantized anomalous Hall effect to high temperature superconductivity."

Who: COLLOQUIUM. Qikun Xue, Professor of Physics, Vice President for Research,Tsinghua University, China

Place: nanoGUNE seminar room, Tolosa Hiribidea 76, Donostia - San Sebastian

Date: Thursday, 3 September 2015, 11:00

Prof. Qi-Kun Xue received his PhD from Institute of Physics, the Chinese Academy of Sciences (CAS) in 1994. From 1994 to 2000, he worked as a Research Associate at IMR, Tohoku University, Japan and a visiting Assistant Professor at Department of Physics, North Carolina State University, USA. He became a professor at Institute of Physics, CAS in 1999. He was elected into The Chinese Academy of Sciences in 2005. Since 2005, he has been a chair professor in Department of Physics, Tsinghua University.

He is one of the most successful scientist in combining MBE growth of novel materials (Topological Insulators, Superconductors, including Iron based) with in-situ characterization by photoemission and scanning tunnelling microscopy/spectroscopy. This rendered him with recognition in the surface science community, as was one of the few groups accessing to mesoscopic phenomena of correlated charges and spins in model and atomically clean systems.

In particular, he investigates  low-dimensional and interface-related high temperature superconductivity, and quantum phenomena in topological insulators.   Among many different findings, his group realized experimentally the quantized anomalous Hall effect in magnetically doped topological insulator in 2013.
