Moiré excitons: from programmable quantum emitter arrays to spin-orbit coupled artificial lattices
Hongyi Yu, Gui-Bin Liu, Jianju Tang +2
Highly uniform and ordered nanodot arrays are crucial for high performance quantum optoelectronics including new semiconductor lasers and single photon emitters, and for synthesizi…
Optical selection rules for excitonic Rydberg series in the massive Dirac cones of hexagonal 2D materials
Pu Gong, Hongyi Yu, Yong Wang +1
We investigate the optical transition selection rules for excitonic Rydberg series formed in massive Dirac cones. The entanglement of the exciton envelop function with the pseudosp…
Unusual Exciton-Phonon Interactions at van der Waals Engineered Interfaces
Colin M. Chow, Hongyi Yu, Aaron M. Jones +6
Raman scattering is a ubiquitous phenomenon in light-matter interactions which reveals a material's electronic, structural and thermal properties. Controlling this process would en…
Interlayer Exciton Optoelectronics in a 2D Heterostructure p-n Junction
Jason S. Ross, Pasqual Rivera, John Schaibley +9
Semiconductor heterostructures are backbones for solid state based optoelectronic devices. Recent advances in assembly techniques for van der Waals heterostructures has enabled the…
Phonon-assisted oscillatory exciton dynamics in monolayer MoSe2
Colin M. Chow, Hongyi Yu, Aaron M. Jones +6
In monolayer semiconductor transition metal dichalcogenides, the exciton-phonon interaction is expected to strongly affect the photocarrier dynamics. Here, we report on an unusual…
