Fig. 6 — a Power dependence of the normalized PL spectra of interlayer excitons in a MoSe₂/WSe₂ heterobilayer³⁰. b Spatial dependence of the normalized PL intensity of interlayer excitons for different incident powers (10, 100, and 1000 μW) at 4 K³⁰. The white outlines show the MoSe₂/WSe₂ heterostructure area. The laser excitation spot is fixed at the top left of the sample. Scale bar, 5 μm. c Normalized PL intensity of interlayer excitons versus distance from the excitation point under different excitation powers³⁰. d Time-dependent electroluminescence (EL) intensity of the neutral (orange, ~150 ns) and charged (blue, ~25 ns) interlayer excitons in the MoSe₂/WSe₂ heterobilayer³⁰. e EL energy of the interlayer exciton versus the electric field (E_hs) applied vertically to the MoSe₂/WSe₂ heterostructure³⁰. a–e Reprinted with permission from ref. ³⁰ [American Association for the Advancement of Science]
