Abstract

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.
