Laser-induced topological spin switching in a 2D van der Waals magnet
Maya Khela, Maciej Dabrowski, Safe Khan +6
Two-dimensional (2D) van der Waals (vdW) magnets represent one of the most promising horizons for energy-efficient spintronic applications because their broad range of electronic,…
Harnessing Exciton-Exciton Annihilation in Two-Dimensional Semiconductors
Eric Linardy, Dinesh Yadav, Daniele Vella +6
Strong many-body interactions in two-dimensional (2D) semiconductors give rise to efficient exciton-exciton annihilation (EEA). This process is expected to result in the generation…
Tailoring Magnetic Anisotropy in CrGeTe by Electrostatic Gating
Ivan. A. Verzhbitskiy, Hidekazu Kurebayashi, Haixia Cheng +4
Electrical control of magnetism of a ferromagnetic semiconductor offers exciting prospects for future spintronic devices for processing and storing information. Here, we report obs…
Phase coherent transport in bilayer and trilayer MoS2
Leiqiang Chu, Indra Yudhistira, Hennrik Schmidt +3
Bilayer MoS2 is a centrosymmetric semiconductor with degenerate spin states in the six valleys at the corners of the Brillouin zone. It has been proposed that breaking of this inve…
Suppressed out-of-plane polarizability of free excitons in monolayer WSe
Ivan A. Verzhbitskiy, Daniele Vella, Kenji Watanabe +2
Monolayer semiconductors are atomically thin quantum wells with strong confinement of electrons in two-dimensional (2D) plane. Here, we experimentally study the out-of-plane polari…
Enhancing charge-density-wave order in 1T-TiSe2 nanosheet by encapsulation with hexagonal Boron Nitride
Linjun Li, WeiJie Zhao, Bo Liu +3
Layered transition metal dichalcogenides (TMDs) provide an ideal platform for exploring the effects of dimensionality on correlated electronic phases such as charge density wave (C…
