Determining the phase diagram of atomically thin layered antiferromagnet CrCl
Zhe Wang, Marco Gibertini, Dumitru Dumcenco +4
Changes in the spin configuration of atomically-thin, magnetic van-der-Waals multilayers can cause drastic modifications in their opto-electronic properties. Conversely, the opto-e…
Spin-flop transition in atomically thin MnPS crystals
Gen Long, Hugo Henck, Marco Gibertini +6
The magnetic state of atomically thin semiconducting layered antiferromagnets such as CrI and CrCl can be probed by forming tunnel barriers and measuring their resistance a…
Multi-frequency Shubnikov-de Haas oscillations in topological semimetal PtHgSe
Diego Mauro, Hugo Henck, Marco Gibertini +4
Monolayer jacutingaite (PtHgSe) has been recently identified as a candidate quantum spin Hall system with a 0.5 eV band gap, but no transport measurements have been perform…
Bulk and surface electronic structure of the dual-topology semimetal Pt2HgSe3
I. Cucchi, A. Marrazzo, E. Cappelli +12
We report high-resolution angle resolved photoemission measurements on single crystals of Pt2HgSe3 grown by high-pressure synthesis. Our data reveal a gapped Dirac nodal line whose…
Emergent dual topology in the three-dimensional Kane-Mele PtHgSe
Antimo Marrazzo, Nicola Marzari, Marco Gibertini
Recently, the very first large-gap Kane-Mele quantum spin Hall insulator was predicted to be monolayer jacutingaite (PtHgSe), a naturally-occurring exfoliable mineral disco…
Intrinsic edge excitons in two-dimensional MoS
Pino D'Amico, Marco Gibertini, Deborah Prezzi +4
Using accurate first-principles calculations based on many-body perturbation theory we predict that two-dimensional MoS hosts edge excitons with universal character, intrinsic…
