  • This work advances excitonic optoelectronics by demonstrating electrically tunable cavity coupling of interlayer excitons in a van der Waals heterobilayer. Through electrostatic control, a 5-fold increase in exciton lifetime and a 50-fold boost in photoluminescence intensity have been achieved, which highlights the role of in-plane optical dipoles in weak coupling and provides momentum-resolved insights into exciton emission.

  • The dipole-dependent propagation of hybrid excitons in a van der Waals heterostructure containing a WSe2 bilayer is characterized by modulating the layer hybridization and interplay between many-body interactions of excitons with an applied vertical electric field.

  • 2D semiconductors offer a promising platform for the realization of compact and CMOS-compatible optoelectronic components. Here, the authors report the realization of light-emitting diodes based on 2D WSe2 integrated with a planar cavity, showing the electrical control of the emission angle and polarization at room temperature.

  • Spatially and temporally resolved exciton diffusion experiments on a two-dimensional WSe2/hBN/MoSe2 heterostructure are reported, where an excitation-power-dependent exciton diffusion pattern is observed and phenomena with dipole–dipole repulsive interaction are quantitatively modelled.

  • The ability to control interlayer excitons in van der Waals heterostructures provides a practical way to address the spin and valley degrees of freedom in solid-state devices. This Review surveys the recent progress in this field, with a focus on devices and engineering techniques.
