First-order magnetic phase-transition of mobile electrons in monolayer MoS $_{2}$

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 $_{2}$ . 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 $> 1 0^{3}$ $cts/s$ under…

Spin-Polarized Electrons in Monolayer MoS $_{2}$

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…
