摘要
It has recently been predicted that the surface plasmons are allowed to exist on the interface between a topological insulator and vacuum. Surface plasmons can be employed to enhance the optical emission from various illuminants. Here, we study the photoluminescence properties of the ZnO/Bi 2Te3 hybrid structures. Thin flakes of Bi 2Te3, a typical three-dimensional topological insulator, were prepared on ZnO crystal surface by mechanical exfoliation method. The ultraviolet emission from ZnO was found to be enhanced by the Bi 2Te3 thin flakes, which was attributed to the surface plasmon - photon coupling at the Bi2Te3/ZnO interface.
