Research Profile

The research topics in Dr Zhang’s group are the fabrication of low dimensional materials such as metal thin films, high quality graphene etc, and the investigation of their atomic structures, electronic structures and novel physical/chemical properties.

In general, the techniques involved in these researches are scanning tunneling microscope (STM), atomic force microscope (AFM), angle resolved photoemission spectroscopy (ARPES), Raman spectroscopy and so on.  

Now, we are studying atomic structures and electronic properties of graphene prepared using various methods such as chemical vapor deposition on metal foils or single crystals, and thermal decomposition of SiC(0001). We further investigate the fundamental growth mechanisms of graphene at the as-grown states by STM.  Moreover, we research the assembly of organic molecules on few layer graphene for modifying the carrier mobility and the unique size effects. We also fabricate some novel systems like magnets /graphene and organism/graphene for exploring their unique electronic, magnetic and transport properties.
