In our recent paper, we have shown that interlayer excitons in bilayer MoS₂ exhibit both a high oscillator strength and highly tunable energies in an applied electric field. Owing to this very large tunability, we were able to optically probe the interaction between intra- and interlayer excitons as they were energetically tuned into resonance. These results have been published in Nature Nanotechnology. More details can also be read at UniNews.
