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…
Tunable Electronic Structure in Gallium Chalcogenide van der Waals Compounds
Brian Shevitski, Søren Ulstrup, Roland J. Koch +8
Transition metal monochalcogenides comprise a class of two-dimensional materials with electronic band gaps that are highly sensitive to material thickness and chemical composition.…
Time- and momentum-resolved photoemission studies using time-of-flight momentum microscopy at a free-electron laser
Dmytro Kutnyakhov, Rui Patrick Xian, Maciej Dendzik +38
Time-resolved photoemission with ultrafast pump and probe pulses is an emerging technique with wide application potential. Real-time recording of non-equilibrium electronic process…
Direct observation of minibands in twisted heterobilayers
Søren Ulstrup, Roland J. Koch, Simranjeet Singh +8
Stacking two-dimensional (2D) van der Waals materials with different interlayer atomic registry in a heterobilayer causes the formation of a long-range periodic superlattice that m…
Imaging microscopic electronic contrasts at the interface of single-layer WS with oxide and boron nitride substrates
Søren Ulstrup, Roland J. Koch, Daniel Schwarz +7
The electronic properties of devices based on two-dimensional materials are significantly influenced by interactions with substrate and electrode materials. Here, we use photoemiss…
