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…
Band energy landscapes in twisted homobilayers of transition metal dichalcogenides
Fábio Ferreira, Samuel Magorrian, Vladimir Enaldiev +2
Twistronic assembly of 2D materials employs the twist angle between adjacent layers as a tuning parameter for designing the electronic and optical properties of van der Waals heter…
Weak ferroelectric charge transfer in layer-asymmetric bilayers of 2D semiconductors
F. Ferreira, V. V. Enaldiev, V. I. Fal'ko +1
In bilayers of two-dimensional (2D) semiconductors with stacking arrangements which lack inversion symmetry charge transfer between the layers due to layer-asymmetric interband hyb…
Piezoelectric networks and ferroelectric moiré superlattice domains in twistronic WS/MoS and WSe/MoSe bilayers
V. V. Enaldiev, F. Ferreira, S. J. Magorrian +1
Twistronic van der Waals heterostrutures offer exciting opportunities for engineering optoelectronic properties of nanomaterials. Here, we use multiscale modeling to study trapping…
Ghost anti-crossings caused by interlayer umklapp hybridization of bands in 2D heterostructures
Abigail J. Graham, Johanna Zultak, Matthew J. Hamer +13
In two-dimensional heterostructures, crystalline atomic layers with differing lattice parameters can stack directly one on another. The resultant close proximity of atomic lattices…
Broken mirror symmetry in excitonic response of reconstructed domains in twisted MoSe/MoSe bilayers
Jiho Sung, You Zhou, Giovanni Scuri +15
Structural engineering of van der Waals heterostructures via stacking and twisting has recently been used to create moiré superlattices, enabling the realization of new optical and…
Crossover from weakly indirect to direct excitons in atomically thin films of InSe
Adrián Ceferino, Kok Wee Song, Samuel J. Magorrian +2
We perform a theory analysis of the spectra of the lowest energy and excited states of the excitons in few-layer atomically thin films of InSe taking into acco…
Stacking domains and dislocation networks in marginally twisted bilayers of transition metal dichalcogenides
V. V. Enaldiev, V. Zólyomi, C. Yelgel +2
We apply a multiscale modeling approach to study lattice reconstruction in marginally twisted bilayers of transition metal dichalcogenides (TMD). For this, we develop DFT-parametri…

Control over the electronic spectrum at low energy is at the heart of the functioning of modern advanced electronics: high electron mobility transistors, semiconductor and Capasso…
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 -tight-binding model for intersubband optics in atomically thin InSe films

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…
Spin-orbit coupling, optical transitions, and spin pumping in mono- and few-layer InSe
S. J. Magorrian, V. Zólyomi, V. I. Fal'ko
We show that spin-orbit coupling (SOC) in InSe enables the optical transition across the principal band gap to couple with in-plane polarized light. This transition, enabled by $p_…
