Quantum transport across normal-superlattice-normal graphene junctions: Fabry-Pérot interference, Hofstadter butterfly, and supersnake states
Che-Pin Hsu, Alina Mreńca-Kolasińska, Aitor Garcia-Ruiz +4
Electrostatic modulation of graphene provides a tunable route to engineering miniband structures. We perform quantum transport simulations on a gate-defined graphene superlattice j…
Electronic Reconstruction at the Quasicrystal-Moiré Crossover in Twisted Bilayer Graphene
Kuo-En Chang, Aitor Garcia-Ruiz, Ta-Lei Chou +11
Large twist angles in twisted bilayer graphene are widely expected to be electronically trivial, with negligible interlayer coupling and no electronic reconstruction, in contrast t…
Efficient Magnetic Spin-Filtering and Persistent Spin-Currents in Lifshitz-Transitioned Altermagnets: A Route to Open-Orbit Spintronics
Wun-Hao Kang, Yu-Ting Hsiao, Jozef Genzor +3
Altermagnets offer a unique venue for spin transport due to their vanishing net magnetization and momentum-dependent spin splitting. We demonstrate that a homotopic Lifshitz transi…
Scalable tight-binding model for strained graphene
Ming-Hao Liu, Christophe De Beule, Alina Mreńca-Kolasińska +4
We generalize the scalable tight-binding model for graphene, which allows for efficient quantum transport simulations in the Dirac regime, to account for elastic strain. We show th…
Dimensional and doping stability of Peierls charge density waves in arrays of coupled one-dimensional chains
Aitor Garcia-Ruiz, Che-Pin Hsu, Ming-Hao Liu +1
The Peierls instability, the spontaneous dimerization of a one-dimensional metallic chain at half filling, is a paradigmatic mechanism for charge-density-wave (CDW) formation. Here…
Anisotropic transport in ballistic bilayer graphene cavities
Florian Schoeppl, Alina Mrenca-Kolasinska, Ming-Hao Liu +3
Closing the gap between ray tracing simulations and experimentally observed electron jetting in bilayer graphene (BLG), we study all-electronic, gate-defined BLG cavities using tig…
Gate-Tunable Resonances and 1D Channel in a Graphene Nanoslide
Christophe De Beule, Ming-Hao Liu, Bart Partoens +1
We present a theory of the graphene nanoslide, a fundamental device for graphene straintronics that realizes a single pseudogauge barrier. We solve the scattering problem in closed…
Pseudomagnetic focusing of valley-polarized beams in strained graphene
Alina Mreńca-Kolasińska, Christophe De Beule, Jia-Tong Shi +4
In addition to spin, the low-energy charge carriers in graphene have two inequivalent valley flavors K and K' related by time-reversal symmetry, which can potentially serve as carr…
Magnetic Field-Induced Polar Order in Monolayer Molybdenum Disulfide Transistors
Duxing Hao, Wen-Hao Chang, Yu-Chen Chang +11
In semiconducting monolayer transition metal dichalcogenides (ML-TMDs), broken inversion symmetry and strong spin-orbit coupling result in spin-valley lock-in effects so that the v…
Four-band effective square lattice model for Bernal-stacked bilayer graphene
Szu-Chao Chen, Alina Mreńca-Kolasińska, Ming-Hao Liu
Bernal-stacked bilayer graphene (BLG) provides an ideal basis for gate-controlled, and free of etching, electronic devices. Theoretical modeling of realistic devices is an essentia…
Magnetotransport Signatures of the Radial Rashba Spin-Orbit Coupling in Proximitized Graphene
Wun-Hao Kang, Michael Barth, Aitor Garcia-Ruiz +3
Graphene-based van der Waals heterostructures take advantage of tailoring spin-orbit coupling (SOC) in the graphene layer by proximity effect. At long-wavelength -- saddled by the…
Fractal Quantum Transport on MoS2 Superlattices: a System with Tunable Symmetry
Aitor Garcia-Ruiz, Ming-Hao Liu
Electron doping is an excellent tuning knob to explore different phases of matter in two-dimensional (2D) materials. For example, tuning the Fermi level at a van Hove singularity i…
