Interlayer excitons, electron-hole pairs bound across two monolayer van der Waals semiconductors, offer promising electrical tunability and localizability. Because such excitons display weak overlap, most studies have examined only the lowest-energy through photoluminescence. We directly measured dielectric response of interlayer which we accessed using their static electric dipole moment. thereby determined an intrinsic radiative lifetime 0.40 nanoseconds for lowest direct-gap exciton in a tungsten diselenide/molybdenum diselenide heterostructure. found that differences field twist angle induced trends transition strengths energies, could be related to wave function moiré confinement, atomic reconstruction. Through comparison with photoluminescence spectra, this study identifies momentum-indirect emission mechanism. Characterization absorption is key applications relying on light-matter interactions.

Moiré lattices formed in twisted van der Waals bilayers provide a unique, tunable platform to realize coupled electron or exciton unavailable before. While twist angle between the bilayer has been shown be critical parameter engineering moiré potential and enabling novel phenomena electronic systems, systematic experimental study as function of is still missing. Here we show that not only are excitons robust even large angles, but also properties dependant on, controllable by, reciprocal lattice period via twist-angle tuning. From dependence, furthermore obtain effective mass interlayer inter-layer tunneling strength, which difficult measure experimentally otherwise. These findings pave way for understanding rich moiré-lattice induced angle-twisted semiconductor heterostructures.
