WebHere, we predict that a high-quality graphene bilayer aligned with an hBN substrate features T 2-dependent resistivity caused by umklapp electron-electron (Uee) scattering from the moir'e superlattice, that is, a momentum kick by Bragg scattering experienced by a pair of electrons. Substantial Uee scattering appears upon p-doping of the bilayer ... WebTwo dimensional hexagonal boron nitride (2D-hBN), an isomorph of graphene with a very similar layered structure, is uniquely featured by its exotic opto-electrical properties together with mechanical robustness, thermal stability, and chemical inertness. It is thus extensively studied for application in fiel Recent Review Articles
