Origin of contact polarity at metal-2D transition metal dichalcogenide interfaces
npj 2D Materials and Applications, 2022 Using state-of-the-art ab initio GW many-body perturbation theory calculations, we show that monolayer MoS2 on Au is a p-type contact, in contrast to the vast majority of theoretical predictions using density functional theory.
