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…
Filtering the photoluminescence spectra of atomically thin semiconductors with graphene
Etienne Lorchat, Luis E. Parra López, Cédric Robert +6
Atomically thin semiconductors made from transition metal dichalcogenides (TMDs) are model systems for investigations of strong light-matter interactions and applications in nanoph…
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…
Rigid-layer Raman-active modes in -layer Transition Metal Dichalcogenides: interlayer force constants and hyperspectral Raman imaging
Guillaume Froehlicher, Etienne Lorchat, Olivia Zill +2
We report a comparative study of rigid layer Raman-active modes in -layer transition metal dichalcogenides. Trigonal prismatic (2Hc, such as MoSe, MoTe, WS, WSe)…
Conductance oscillations in graphene/nanoclusters hybrid material: towards large area single electron devices
Florian Godel, Louis Donald Notemgnou Mouafo, Guillaume Froehlicher +5
Large assemblies of self-organized aluminum nanoclusters embedded in an oxide layer are formed on graphene templates and used to build tunnel-junction devices. Unexpectedly, single…
