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…
Persistent Fluctuating Superconductivity and Planckian Dissipation in Fe(Te,Se)
Jonathan Stensberg, Pok Man Tam, Xiaoyu Yuan +11
Increasingly intricate phase diagrams in new classes of superconductors host fascinating interactions between superconductivity, diverse quantum phases, and quantum critical dynami…
Nanosculpting lateral weak link junctions in superconducting Fe(Te,Se)/Bi2Te3 with focused Si++ ions and implications on vortex pinning
Debarghya Mallick, Sujoy Ghosh, An Hsi Chen +10
Superconductor-normal-superconductor (SC-N-SC) weak links enable Cooper-pair tunneling and serve as Josephson junctions (JJs) used in modern superconducting qubits. Conventional JJ…
Programmable phase selection between altermagnetic and non-centrosymmetric polymorphs of MnTe on InP via molecular beam epitaxy
An-Hsi Chen, Parul R. Raghuvanshi, Jacob Cook +19
Phase selecting nearly degenerate crystalline polymorphs during epitaxial growth can be challenging yet is critical to targeting physical properties for specific applications. Here…
Reversible Modification of Rashba States in Topological Insulators at Room Temperature by Edge Functionalization
