Van Der Waals Materials

The strain in hybrid van der Waals heterostructures, made of two distinct two-dimensional van der Waals materials, offers an interesting handle on their corresponding electronic band structure. Such strain can be engineered by changing the relative crystallographic orientation between the constitutive monolayers, notably, the angular misorientation, also known as the “twist angle”. By combining angle-resolved photoemission spectroscopy with density functional theory calculations, we investigate here the band structure of the WS2/graphene heterobilayer for various twist angles. Despite the relatively weak coupling between WS2 and graphene, we demonstrate that the resulting strain quantitatively affects many electronic features of the WS2 monolayers, including the spin-orbit coupling strength. In particular, we show that the WS2 spin-orbit splitting of the valence band maximum at K can be tuned from 430 to 460 meV. Our findings open perspectives in controlling the band dispersion of van der Waals materials.

Cone Approximation

Starting from the Holstein model, we have investigated the effects of Rashba spin–orbit coupling (RSOC) on density of states (DOS), electronic heat capacity (EHC) and magnetic susceptibility (MS) of boron nitride-doped (BN-doped) graphene beyond the Dirac cone approximation within the Green’s function approach. By using the self-consistent perturbation theory, retarded self-energy can be calculated. We have found that the band gap (the peak of EHC and MS) of the system increases (decreases) with RSOC and electron–phonon (e–ph) interaction. Also, the Schottky anomaly moves only to the higher temperatures for strong RSOCs and e–ph interactions. Also, our results show that the response of the system to an external magnetic field is scaled down in the presence of RSOC and e–ph interaction.

Metal Dichalcogenides

Transition metal dichalcogenides (TMDs) display unique properties in their monolayer structures, namely a direct band-gap transition, which becomes a promising candidate for optoelectronics applications. Among them, WS2 exhibits strong spin-orbit interaction which splits the excitonic peaks as observed in the experimental data up to ~400 meV. Unlike the other TMDs, the first excitonic peak A is very sharp for WS2, while the secondary peak B is broader with smaller relative intensity. In this paper, we perform first-principles calculations on the electronic band structure and solve the Bethe-Salpeter equation for the complex dielectric function of monolayer WS2 to study the effects of spin-orbit coupling on its excitonic structures. To resolve the excitonic peaks, in particular the B peak, we implement the double-grid method. We discuss the effects of electron-hole interaction on the absorption spectrum by comparing it with that calculated at the independent-particle level.
