TL;DR: A monolayer of van der Walls material PtBi2 is proved as a two-dimensional multiple topological insulator and topological protection of these channels is confirmed by directly demonstrating their robustness to variations of crystal orientation, edge geometry and sample temperature.

TL;DR: In this article, the authors used density functional theory combined with Monte Carlo simulations to predict the cleavage energies of monolayers 2 H - GdX 2 (X, Y, Cl, Br, I) and GdXY.

TL;DR: In this article, the atomic structures, adsorption energies, and spin polarizations of lanthanide atoms adsorbed on the single and double vacancies in graphene are investigated systematically by the first- principles calculations.

TL;DR: In this article, the atomic and electronic structures of CrI3 zigzag nanoribbons were studied by using first-principles calculations and it was shown that edge states play an important role in their electronic structures.
