Gate-tunable polariton reflection in hBN-graphene heterostructures
Siyuan DaiAuburn University – Auburn, Alabama, USA_______________________________________ The variation of optical momentum determines light propagation across material interfaces. Evident momentum mismatch at the two sides of the interface results in inefficient energy transfer due to the lack of phase matching, thereby causing light reflection or scattering. In this work, we demonstrate an electrically tunable polaritonic…
