Angle-dependence of interlayer coupling in twisted transition metal dichalcogenide heterobilayers

W. T. Geng, V. Wang, J. B. Lin +2

We reveal by first-principles calculations that the interlayer binding in a twisted MoS2/MoTe2 heterobilayer decreases with increasing twist angle, due to the increase of the inter…

Moiré potential, lattice corrugation, and band gap spatial variation in a twist-free MoS2/MoTe2 heterobilayer

W. T. Geng, V. Wang, Y. C. Liu +2

To have a fully ab initio description of the Moiré pattern in a transition metal dichalcogenide heterobilayer, we have carried out density functional theory calculations, taking ac…
