Enhanced light-matter interaction in an atomically thin semiconductor coupled with dielectric nano-antennas

Abstract

Dielectric nano-antennas may be used as a platform for boosting light-matter coupling in 2D semiconductors. Here, the authors demonstrate the coupling of atomically thin WSe$${}_{2}$$ 2 with low-loss, high-refractive-index GaP nano-antennas and observe a 10000-fold WSe$${}_{2}$$ 2 photoluminescence enhancement.
