Current Research

  • Fundamental studies of spin, charge and phonon transport in graphene, phosphorene and 2D van der Waals heterostructures.

  • Semiconductor device application of graphene and other 2D crystals , e.g. Ferroelectric-graphene non-volatile memory, Black phosphorus effect transistor.

  • Graphene based biomedical applications: cellular force sensing, stem cell differentiation and growth.

  • Energy storage applications of nano-porous graphene and its derivatives, e.g. Supercapacitors.
