Direct visualization and control of SrOx segregation on semiconducting Nb doped SrTiO3 (100) surface
Hyang Keun Yoo, Daniel Schwarz, Soren Ulstrup +6
We investigated how SrOx segregates on a Nb doped SrTiO3 (100) surface by in air annealing. Using atomic force and photoemission electron microscopes, we can directly visualize the…
Spectroscopic view of ultrafast charge carrier dynamics in single- and bilayer transition metal dichalcogenide semiconductors
P. Majchrzak, K. Volckaert, A. G. Cabo +24
The quasiparticle spectra of atomically thin semiconducting transition metal dichalcogenides (TMDCs) and their response to an ultrafast optical excitation critically depend on inte…
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…
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…
Pnictogens Allotropy and Phase Transformation during van der Waals Growth
Matthieu Fortin-Deschênes, Hannes Zschiesche, Tevfik O. Menteş +13
Pnictogens have multiple allotropic forms resulting from their ns2 np3 valence electronic configuration, making them the only elemental materials to crystallize in layered van der…
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…
