Research Area & contribution:
Highly recognized for major contributions in surface physics, low dimensional spin dynamics field and in situ ultrafast low energy electron microscopy as an experimentalist in the world.
Discovered a new Body-Centered-Cubic Ni nanostructure by Molecular Beam Epitaxy (Tang et al., 2002; Tian et al., 2005).
Breakthrough in discovery of the first surface magnon dispersion in bi-and-monolayer Fe system provided great opportunity for scientists to understand the origin of spin interaction in the low dimensional systems (Tang et al., 2007; Prokop, et al., 2009). The surface magnon energy is almost 10 times less at the surface Brillouin zone boundary than the theoretical prediction since 1930.
Envisaged the importance of III-V semiconductor in the future spintronics, developed a unique III-V surface microscopy with his colleagues, a novel technique to probe and manipulate surface dynamics for III-V nanoscale in real space and real time (Jesson, Tang et al., 2010, 2011). These works have been published in prestigious physics journals such as Science and Physical Review Letters.
Designed and obtained multi Million $ national funding in China for developing an ultrafast spin polarized low energy electron microscopy (Wan et al., Ultramicroscopy 2016). The big success of the project achieves the first aberration corrected SPLEEM and ultrafast high resolution spin polarized LEEM, and foster discoveries in the ultrafast surface imaging field (Yu et al., Ultramicroscopy 2020). Act as Chairman for prestigious international LEEMPEEM-11 workshop in 2018 at Chongqing and serve as Guest Editor of Ultramicroscopy.
Recent major role as Chief Scientist and director on Ultrafast Transient Material Science Facility (UTMSF) . The original idea and proposal have been approved by Chongqing government after evaluation by National Development and Reform Commission (NDRC) which will focus on Ultrafast Science by coupling ultrafast electron microscopies and short pulse synchrotron radiation in the next two decade. The UTMSF will be one of key technique to understand nature and origin of life in time domain.
