Engineering of Interlayer Exciton Physics
Excitonic states provide a powerful platform to probe correlated electronic phases, explore many-body phenomena, and serve as building blocks for future excitonic devices. Interlayer excitons in bilayer and trilayer van der Waals systems are particularly promising due to their long lifetimes, strong dipolar interactions, and high tunability. Their properties depend critically on the rotational alignment of the layers and the local atomic arrangement, making structural precision a key factor in defining their behavior. Our research investigates how these structural parameters, together with optical and electrical excitation pathways, shape the formation, charge-transfer efficiency, and dynamics of interlayer excitons and related complexes. By systematically controlling alignment, hybridization, and tunneling, we aim to uncover new strategies for manipulating excitonic processes towards the design of functional excitonic devices.
