Tunable spin-orbit coupling in two-dimensional InSe
A. Ceferino, S. J. Magorrian, V. Zólyomi +7
We demonstrate that spin-orbit coupling (SOC) strength for electrons near the conduction band edge in few-layer -InSe films can be tuned over a wide range. This tunability is th…
Multifaceted moiré superlattice physics in twisted WSe bilayers
S. J. Magorrian, V. V. Enaldiev, V. Zólyomi +3
Lattice reconstruction in twisted transition-metal dichalcogenide (TMD) bilayers gives rise to piezo- and ferroelectric moiré potentials for electrons and holes, as well as a modul…
Raman spectroscopy of GaSe and InSe post-transition metal chalcogenides layers
Maciej R. Molas, Anastasia V. Tyurnina, Viktor Zólyomi +9
III-VI post-transition metal chalcogenides (InSe and GaSe) are a new class of layered semiconductors, which feature a strong variation of size and type of their band gaps as a func…

Gergő Kukucska, Viktor Zólyomi, János Koltai
We present a new method to compute resonance Raman spectra based on ab initio level calculations using the frequency-dependent Placzek approximation. We illustrate the efficiency o…
Infrared-to-violet tunable optical activity in atomic films of GaSe, InSe, and their heterostructures
Daniel J. Terry, Viktor Zólyomi, Matthew Hamer +11
Two-dimensional semiconductors - atomic layers of materials with covalent intra-layer bonding and weak (van der Waals or quadrupole) coupling between the layers - are a new class o…
Hybrid kp tight-binding model for subbands and infrared intersubband optics in few-layer films of transition-metal dichalcogenides: MoS, MoSe, WS and WSe
David A. Ruiz-Tijerina, Mark Danovich, Celal Yelgel +2
We present a density functional theory parametrized hybrid kp tight binding model for electronic properties of atomically thin films of transition-metal dichalcogenides, 2H-…
Resonance Raman spectroscopy of silicene and germanene
Gergő Kukucska, Viktor Zólyomi, János Koltai
We model Raman processes in silicene and germanene involving scattering of quasiparticles by, either, two phonons, or, one phonon and one point defect. We compute the resonance Ram…
Tunable Berry curvature, valley and spin Hall effect in Bilayer MoS
Andor Kormányos, Viktor Zólyomi, Vladimir I. Fal'ko +1
The chirality of electronic Bloch bands is responsible for many intriguing properties of layered two-dimensional materials. We show that in bilayers of transition metal dichalcogen…
