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…
Terahertz Landau level spectroscopy of Dirac fermions in millimeter-scale twisted bilayer graphene
Benjamin F. Mead, Spenser Talkington, An-Hsi Chen +8
Exotic electronic physics including correlated insulating states and fractional Chern insulators have been observed in twisted bilayer graphene in a magnetic field when the Fermi v…
Wafer-scale Programmed Assembly of One-atom-thick Crystals
Seong-Jun Yang, Ju-Hyun Jung, Eunsook Lee +11
Crystalline films offer various physical properties based on the modulation of their thicknesses and atomic structures. The layer-by-layer assembly of atomically thin crystals prov…
Step-directed Epitaxy of Uni-directional Hexagonal Boron Nitride on Vicinal Ge(110)
Ju-Hyun Jung, Chao Zhao, Seong-Jun Yang +8
Insulating hexagonal boron nitride (hBN) films with precisely controlled thickness are ideal dielectric components to modulate various interfaces in electronic devices. To achieve…
All-Dry Transfer of Graphene Film by Van der Waals Interactions
Seong-Jun Yang, Shinyoung Choi, Francis Okello Odongo Ngome +3
We report a method that uses van der Waals interactions to transfer continuous, high-quality graphene films from Ge(110) to a different substrate held by hexagonal boron nitride ca…
