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…
Hybrid -tight-binding model for intersubband optics in atomically thin InSe films
Samuel J. Magorrian, Adrian Ceferino, Viktor Zólyomi +1
We propose atomic films of n-doped -InSe as a platform for intersubband optics in the infrared (IR) and far infrared (FIR) range, coupled to out-of-plane polarized light. Depend…
