研究介绍 

Research Interest



The  study of low-dimensional quantum materials is very important, not only  being the  basis for the development of low energy consumpition and high  speed electronic devices, but also the key to  break through bottlenecks of the existing materials. We mainly use laser molecular beam epitaxy to manipulate the stacked lego structure of  single atomic  layers, develop new correlated eletron materials on the  basis of a single atomic layer, and study physical structures and  mechanisms, including (1) interfacial electronics and spintronics; (2) two-dimensional  freestanding films and soft electronics; (3) synchrotron and neutron  studies of interfacial physics. The goal is to explore  low-dimensional quantum materials and devices to fill future needs in ultra-small size and ultra-fast response electronic/spintronic  applications.


The Laser-MBE facility of our lab

The  group has open positions for post-doctoral fellows, PhD and Master students with excellent working environment. Students and scholars who are interested in conducting cutting-edge research in the fields of condensed matter physics and material physics are welcome to join! Please email Zhai Xiaofang directly.
