Electrically Tunable Excitonic Light Emitting Diodes based on Monolayer WSe2 p-n Junctions
Jason S. Ross, Philip Klement, Aaron M. Jones +9
Light-emitting diodes are of importance for lighting, displays, optical interconnects, logic and sensors. Hence the development of new systems that allow improvements in their effi…
Spin-Layer Locking Effects in Optical Orientation of Exciton Spin in Bilayer WSe2
Aaron M. Jones, Hongyi Yu, Jason S. Ross +6
Coupling degrees of freedom of distinct nature plays a critical role in numerous physical phenomena. The recent emergence of layered materials provides a laboratory for studying th…
Control of Two-Dimensional Excitonic Light Emission via Photonic Crystal
Sanfeng Wu, Sonia Buckley, Aaron M. Jones +9
Monolayers of transition metal dichalcogenides (TMDCs) have emerged as new optoelectronic materials in the two dimensional (2D) limit, exhibiting rich spin-valley interplays, tunab…
Observation of magnetic field generation via the Weibel instability in interpenetrating plasma flows
C. M. Huntington, F. Fiuza, J. S. Ross +18
Collisionless shocks can be produced as a result of strong magnetic fields in a plasma flow, and therefore are common in many astrophysical systems. The Weibel instability is one c…
Optical Generation of Excitonic Valley Coherence in Monolayer WSe2
Aaron Mitchell Jones, Hongyi Yu, Nirmal Ghimire +9
Due to degeneracies arising from crystal symmetries, it is possible for electron states at band edges ("valleys") to have additional spin-like quantum numbers. An important questio…
Vapor-Solid Growth of High Optical Quality MoS2 Monolayers With Near-Unity Valley Polarization
Sanfeng Wu, Chunming Huang, Grant Aivazian +3
Monolayers of transition metal dichalcogenides (TMDCs) are atomically thin direct-gap semiconductors with potential applications in nanoelectronics, optoelectronics, and electroche…
