Abstract

This talk will review our recent studies on the enhanced emission near ENZ thin film. Our study employs thin homogeneous titanium nitride (TiN) films with ENZ wavelengths in the visible spectrum that match a wide excitation bandwidth of quantum dots and 2D emitters to probe ENZ-emitter interaction. Our results show that the ENZ substrate enhances excitation fields in the MoS2 monolayer and hence enhances its spontaneous emission. This study will enrich the fundamental understanding of spontaneous emission on ENZ substrates that might be useful for the development of advanced nanophotonic light sources.
