Beyond spin models in orbitally-degenerate open-shell nanographenes
J. C. G. Henriques, D. Jacob, A. Molina-Sánchez +3
The study of open-shell nanographenes has relied on a paradigm where spins are the only low-energy degrees of freedom. Here we show that some nanographenes can host low-energy exci…
Strong Coupling of Coherent Phonons to Excitons in Semiconducting Monolayer MoTe
Charles J. Sayers, Armando Genco, Chiara Trovatello +8
The coupling of the electron system to lattice vibrations and their time-dependent control and detection provides unique insight into the non-equilibrium physics of semiconductors.…
Interplay between spin proximity effect and charge-dependent exciton dynamics in MoSe / CrBr van der Waals heterostructures
T. P. Lyons, D. Gillard, A. Molina-Sánchez +9
Semiconducting ferromagnet-nonmagnet interfaces in van der Waals heterostructures present a unique opportunity to investigate magnetic proximity interactions dependent upon a multi…
Orbital Hall Insulating Phase in Transition Metal Dichalcogenide Monolayers
Luis M. Canonico, Tarik P. Cysne, Alejandro Molina-Sanchez +2
We show that H-phase transition metal dichalcogenides (TMDs) monolayers such as MoS and WSe, are orbital Hall insulators. They present very large orbital Hall conductivity…
Spin-layer locking of interlayer excitons trapped in moiré potentials
Mauro Brotons-Gisbert, Hyeonjun Baek, Alejandro Molina-Sánchez +7
Van der Waals heterostructures offer attractive opportunities to design quantum materials. For instance, transition metal dichalcogenides (TMDs) possess three quantum degrees of fr…
Out-of-plane orientation of luminescent excitons in atomically thin indium selenide flakes
Mauro Brotons-Gisbert, Raphaël Proux, Raphaël Picard +5
Van der Waals materials offer a wide range of atomic layers with unique properties that can be easily combined to engineer novel electronic and photonic devices. A missing ingredie…
Ab initio calculations of ultra-short carrier dynamics in 2D materials: valley depolarization in single-layer WSe
Alejandro Molina-Sánchez, Davide Sangalli, Ludger Wirtz +1
In single-layer WSe, a paradigmatic semiconducting transition metal dichalcogenide, a circularly polarized laser field can selectively excite electronic transitions in one of t…
Quantum interference effects in resonant Raman spectroscopy of single- and triple-layer MoTe from first principles
Henrique P. C. Miranda, Sven Reichardt, Guillaume Froehlicher +3
We present a combined experimental and theoretical study of resonant Raman spectroscopy in single- and triple-layer MoTe. Raman intensities are computed entirely from first pri…
Unified description of the optical phonon modes in -layer MoTe
Guillaume Froehlicher, Etienne Lorchat, François Fernique +4
-layer transition metal dichalcogenides provide a unique platform to investigate the evolution of the physical properties between the bulk (three dimensional) and monolayer (qua…
Probing quantum confinement within single core-multishell nanowires
Gema Martínez-Criado, Alejandro Homs, Benito Alén +6
Theoretically core-multishell nanowires under a cross-section of hexagonal geometry should exhibit peculiar confinement effects. Using a hard X-ray nanobeam, here we show experimen…
LDA+U and tight-binding electronic structure of InN nanowires
A. Molina-Sánchez, A. García-Cristóbal, A. Cantarero +2
In this paper we employ a combined {\it ab initio} and tight-binding approach to obtain the electronic and optical properties of hydrogenated InN nanowires. We first discuss InN ba…
