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 ... WebApr 13, 2024 · A simple, highly effective synthesis of tetracyclic pyrano[3,4-b]indoles derivatives from simple 2-indolylmethanols and trione alkenes has been accomplished through oxa-Michael addition-Friedel–Crafts reaction-cyclization cascade promoted by a cheap and green graphene oxide catalyst.
