First-order magnetic phase-transition of mobile electrons in monolayer MoS
Jonas Gaël Roch, Dmitry Miserev, Guillaume Froehlicher +7
Evidence is presented for a first-order magnetic phase transition in a gated two-dimensional semiconductor, monolayer-MoS. The phase boundary separates a spin-polarised (ferrom…
Optical second harmonic generation in encapsulated single-layer InSe
Nadine Leisgang, Jonas G. Roch, Guillaume Froehlicher +4
We report the observation of optical second harmonic generation (SHG) in single-layer indium selenide (InSe). We measure a second harmonic signal of under…
Spin-Polarized Electrons in Monolayer MoS
Jonas G. Roch, Guillaume Froehlicher, Nadine Leisgang +4
The optical susceptibility is a local, minimally-invasive and spin-selective probe of the ground state of a two-dimensional electron gas. We apply this probe to a gated monolayer o…
Quantum confined Stark effect in a MoS monolayer van der Waals heterostructure
Jonas G. Roch, Nadine Leisgang, Guillaume Froehlicher +5
The optics of dangling-bond-free van der Waals heterostructures containing transition metal dichalcogenides are dominated by excitons. A crucial property of a confined exciton is t…
