AbstractLayered materials, such as graphene, transition metal dichacogenides and black
phosphorus have attracted lots of attention recently. They are emerging novel
materials in electronics and photonics, with tremendous potential in
revolutionizing the traditional electronics and photonics industry. Marrying
layered material to the nanophotonics is being proved fruitful. With the recent
emphasis and development of metasurfaces in nanophotonics, atomically thin
materials can find their unique position and strength in this field. In this
article, I will focus on one specific two dimensional material: bilayer
graphene. Basic physics will be reviewed, such as band-gap opening,
electron-phonon interaction, phonon-plasmon interaction and Fano resonances in
the optical response. Moreover, I will review the application of bilayer
graphene as a sensitive and fast photodetector. An outlook will be given in the
final part of the paper.
