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…
Reversible Modification of Rashba States in Topological Insulators at Room Temperature by Edge Functionalization
Wonhee Ko, Seoung-Hun Kang, Qiangsheng Lu +7
Quantum materials with novel spin textures from strong spin-orbit coupling (SOC) are essential components for a wide array of proposed spintronic devices. Topological insulators ha…
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…
Quantized Magneto-Terahertz Effects in the Antiferromagnetic Topological Insulator MnBiTe Thin Films
Xingyue Han, An-Hsi Chen, Matthew Brahlek +1
MnBiTe (MBT) is an ideal platform for studying the interplay between magnetism and topology. Many exotic topological phenomena, such as the quantum anomalous Hall effect an…
Single-layer magnet phase in intrinsic magnetic topological insulators, , far beyond the thermodynamic limit
Deepti Jain, Hee Taek Yi, Xiong Yao +6
The intrinsic magnetic topological insulator (IMTI) family has demonstrated magneto-topological properties dependent…
Interplay between Topological States and Rashba States as Manifested on Surface Steps at Room Temperature
Wonhee Ko, Seoung-Hun Kang, Jason Lapano +7
The unique spin texture of quantum states in topological materials underpins many proposed spintronic applications. However, realizations of such great potential are stymied by per…
