One-dimensional electronic states in a natural misfit structure
Alla Chikina, Gargee Bhattacharyya, Davide Curcio +7
Misfit compounds are thermodynamically stable stacks of two-dimensional materials, forming a three-dimensional structure that remains incommensurate in one direction parallel to th…
Visualizing band structure hybridization and superlattice effects in twisted MoS/WS heterobilayers
Alfred J. H. Jones, Ryan Muzzio, Sahar Pakdel +16
A mismatch of atomic registries between single-layer transition metal dichalcogenides (TMDs) in a two dimensional van der Waals heterostructure produces a moiré superlattice with a…
Electronic Properties of Single-Layer CoO/Au(111)
Ann Julie U. Holt, Sahar Pakdel, Jonathan Rodríguez-Fernández +11
We report direct measurements via angle-resolved photoemission spectroscopy (ARPES) of the electronic dispersion of single-layer CoO. The Fermi contour consists of a large hole…
Hot carrier-assisted switching of the electron-phonon interaction in 1-VSe
Paulina Majchrzak, Sahar Pakdel, Deepnarayan Biswas +20
We apply an intense infrared laser pulse in order to perturb the electronic and vibrational states in the three-dimensional charge density wave material 1-VSe. Ultrafast sna…
Ultrafast triggering of insulator-metal transition in two-dimensional VSe
Deepnarayan Biswas, Alfred J. H. Jones, Paulina Majchrzak +24
Assembling transition metal dichalcogenides (TMDCs) at the two-dimensional (2D) limit is a promising approach for tailoring emerging states of matter such as superconductivity or c…
Moiré induced electronic structure modifications in monolayer VS on Au(111)
Umut Kamber, Sahar Pakdel, Raluca-Maria Stan +11
There is immense interest in how the local environment influences the electronic structure of materials at the single layer limit. We characterize moiré induced spatial variations…
Observation of Electrically Tunable van Hove Singularities in Twisted Bilayer Graphene from nanoARPES
Alfred J. H. Jones, Ryan Muzzio, Paulina Majchrzak +16
The possibility of triggering correlated phenomena by placing a singularity of the density of states near the Fermi energy remains an intriguing avenue towards engineering the prop…
Layer and orbital interference effects in photoemission from transition metal dichalcogenides
Habib Rostami, Klara Volckaert, Nicola Lanata +10
In this work, we provide an effective model to evaluate the one-electron dipole matrix elements governing optical excitations and the photoemission process of single-layer (SL) and…
Momentum-resolved linear dichroism in bilayer MoS
Klara Volckaert, Habib Rostami, Deepnarayan Biswas +19
Inversion-symmetric crystals are optically isotropic and thus naively not expected to show dichroism effects in optical absorption and photoemission processes. Here, we find a stro…
Orbital Selectivity in Hund's metals: The Iron Chalcogenides
N. Lanatà, H. U. R. Strand, G. Giovannetti +3
We show that electron correlations lead to a bad metallic state in chalcogenides FeSe and FeTe despite the intermediate value of the Hubbard repulsion and Hund's rule coupling…
