Weak localization and universal conductance fluctuations in large area twisted bilayer graphene

Spenser Talkington, Debarghya Mallick, An-Hsi Chen +7

We study diffusive magnetotransport in highly p-doped large area twisted bilayer graphene in 1°, 7°, 9° and 20° samples. We report weak localization in twisted bilayer graphene for…
