Current Research

  • Experimental Condensed Matter and Material Science Group: Experimental Condensed Matter
    • Experimental Solid State Physics
      • The emphasis of this research lab is on characterizations and applications of low dimensional materials, particularly emerging low dimensional semiconductors. Recently we focus on optical properties of atomic 2 dimensional (2D) crystals, particularly atomic layers of transition metal dichalcogenides (TMD). We explore the interplay of electron’s spin, valley degrees of freedom and electron-electron interactions with semiconductor optics techniques.
