Non-ohmic to ohmic crossover in the breakdown of the quantum Hall states in graphene under broadband excitations
Torsten Röper, Aifei Zhang, Kenji Watanabe +4
Graphene, through the coexistence of large cyclotron gaps and small spin and valley gaps, offers the possibility to study the breakdown of the quantum Hall effect across a wide ran…
Non-universal localization transition in the quantum Hall effect probed through broken-symmetry states of graphene
Aifei Zhang, Torsten Röper, Manjari Garg +7
The quantum Hall effect hosts quantum phase transitions in which the localization length, that is the size of disorder-induced bulk localized states, is governed by universal scali…
Quantum Hall Antidot as a Fractional Coulombmeter
Mario Di Luca, Emily Hajigeorgiou, Zekang Zhou +6
The detection of fractionally charged quasiparticles, which arise in the fractional quantum Hall regime, is of fundamental importance for probing their exotic quantum properties. W…
Frequency as a Clock: Synchronization and Intrinsic Recovery in Graphene Transistor Dynamics
Victor Lopez-Richard, Igor Ricardo Filgueira e Silva, Gabriel L. Rodrigues +4
Hysteresis and memory effects in graphene field-effect transistors (GFETs) offer unique opportunities for neuromorphic computing, sensing, and memory applications, yet their physic…
Magnetization Dependent In-plane Anomalous Hall Effect in a Low-dimensional System
I-Hsuan Kao, Ravi Kumar Bandapelli, Zhenhong Cui +17
Anomalous Hall Effect (AHE) response in magnetic systems is typically proportional to an out-of-plane magnetization component because of the restriction imposed by system symmetrie…
