To try to summarize our work in the broadest possible terms:

We are growing and then studying new, highly ordered 2D materials on pure single crystal surfaces to study both their intrinsic properties and (new, novel) new emergent properties which come about arise due to different ways these materials can interact with the underlying surface structure. 

We use molecular beam epitaxy (MBE) in ultrahigh vacuum (UHV), multilayer depositions, thermal cycling, electron diffraction (LEED), angle resolved photoemission spectroscopy (ARPES), and scanning tunneling microscopy and spectroscopy (STM, STS) as well as density functional theory (DFT) to characterize how these phenomena manifest themselves in terms of both the final atomic structure and the new electronic band structures and collective effects that arise from them.

While we frequently collect ARPES data with our in-house helium UV light source (21.2 and 40.8 eV) our unique location at the National Synchrotron Radiation Research Facility (NSRRC) in the Hsinchu Science Park in Taiwan allows us to regularly move our system to the beamline for higher intensity and higher energy photon beams. 

Materials we are currently studying include Xenes (graphene's cousins) like germanene and silicene (both single and multilayer structures), superconducting alloys like AuPb and metallic quantum well structures, and ordered organic molecule superstructures of  halogenated forms of picene and other polycyclic aromatic molecules with strong optical properties.

Our results not only provide both discovery and new and deeper insights into emergent properties from these tuned structures, but open the possibilities to next generation materials for quantum computing, photonics and even faster, smaller electronics than traditional CMOS process can provide.
