Ma Xucun, born in November 1971, received her BS degree in Chemistry from Department of Chemistry, Peking University in 1992, received her PhD degree in Physics from Institute of Physics, CAS in 2000. From 2000 to 2002 she worked as a postdoctoral research fellow in Max-Planck-Institut f
r Mikrostrukturphysik, Germany. Currently she is working as a full professor and the group leader in Institute of Physics, CAS. Her main research interests are on the growth and atomic-level control of thin films (including topological insulators), and the novel physical/chemical properties and quantum effects in nanostructures, mainly using molecular beam epitaxy combined scanning tunneling microscopy, and angle-resolved photoemission spectroscopy.
