Vernier Spectrum and Isospin State Control in Carbon Nanotube Quantum Dots
Jameson Berg, Neda Lotfizadeh, Dublin Nichols +4
Commensurability phenomena abound in nature and are typically associated with mismatched lengths, as can occur in quasiperiodic systems. However, not all commensuration effects are…
Nanomechanical Characterization of an Antiferromagnetic Topological Insulator
Shuwan Liu, Su Kong Chong, Dongwook Kim +7
The antiferromagnetic topological insulator MnBi2Te4 (MBT) exhibits an ideal platform to study exotic topological phenomena and magnetic properties. The transport signatures of mag…
Gate-tunable anomalous Hall effect in a 3D topological insulator/2D magnet van der Waals heterostructure
Vishakha Gupta, Rakshit Jain, Yafei Ren +8
We demonstrate advantages of samples made by mechanical stacking of exfoliated van der Waals materials for controlling the topological surface state of a 3-dimensional topological…
Topological Phase Transitions in a Hybridized Three-Dimensional Topological Insulator
Su Kong Chong, Lizhe Liu, Taylor D. Sparks +2
As the thickness of a three-dimensional (3D) topological insulator (TI) becomes comparable to the penetration depth of the surface states, quantum tunneling between surfaces turns…
Landau Levels of Topologically-Protected Surface States Probed by Dual-Gated Quantum Capacitance
Su Kong Chong, Ryuichi Tsuchikawa, Jared Harmer +2
Spectroscopy of discrete Landau levels (LLs) in bulk-insulating three-dimensional topological insulators (3D TIs) in perpendicular magnetic field characterizes the Dirac nature of…
Band-Gap-Dependent Electronic Compressibility of Carbon Nanotubes in the Wigner Crystal Regime
Neda Lotfizadeh, Daniel R. McCulley, Mitchell J. Senger +4
Electronic compressibility, the second derivative of ground state energy with respect to total electron number, is a measurable quantity that reveals the interaction strength of a…
