Breaking of valley degeneracy by magnetic field in monolayer MoSe2
David MacNeill, Colin Heikes, Kin Fai Mak +5
Using polarization-resolved photoluminescence spectroscopy, we investigate valley degeneracy breaking by out-of-plane magnetic field in back-gated monolayer MoSe devices. We ob…
Tightly bound excitons in monolayer WSe2
Keliang He, Nardeep Kumar, Liang Zhao +4
Exciton binding energy and excited states in monolayers of tungsten diselenide (WSe2) are investigated using the combined linear absorption and two-photon photoluminescence excitat…
Possible Topological Superconducting Phases of MoS
Noah F. Q. Yuan, Kin Fai Mak, K. T. Law
Molybdenum disulphide (MoS) has attracted much interest in recent years due to its potential applications in a new generation of electronic devices. Recently, it was shown that…
The Valley Hall Effect in MoS2 Transistors
Kin Fai Mak, Kathryn L. McGill, Jiwoong Park +1
Electrons in 2-dimensional crystals with a honeycomb lattice structure possess a new valley degree of freedom (DOF) in addition to charge and spin. Each valley is predicted to exhi…
