Current Research

Prof. Eda’s research aims to translate unusual condensed matter phenomena into novel technology. His research group studies a range of fundamental and applied physical effects that are unique to two-dimensional (2D) materials derived from ordinary layered compounds such as MoS2.

  • Excitons and polaritons
  • Charge transport
  • Thin film electro-optics
  • Solar energy conversion
  • Crystal phase engineering

Strong coupling between excitons and plasmons gives rise to electromagnetically induced transparency
