This paper demonstrates that applying a strong electric field to twisted bilayer graphene with fixed charge density induces layer-selective hydrogenation and proton transport, enabling the creation of configurable logic gates through independent control of the decoupled electronic systems in each layer.
This study characterizes heat conduction and energy relaxation in an InAs nanowire approaching the clean one-dimensional limit by demonstrating that electron-phonon heat flow scales as , closely matching the theoretical prediction, and identifying a 370 nm characteristic length scale where phonon-mediated transport becomes dominant.
This paper argues that while the quantum Hall effect typically exhibits a linear current-voltage relationship due to Galilean invariance, spatially inhomogeneous electric fields can induce a nonlinear response in quantum Hall liquids through centrifugal forces and vorticity-induced density gradients within a hydrodynamic framework.
This paper proposes that unquenched orbital angular momentum is the physical origin of spin inertia, deriving the associated inertia parameter from a two-sublattice model that agrees with experimental values in cobalt and offers specific signatures to verify this mechanism while distinguishing it from spurious optical modes.
This study demonstrates that a 2D network of TbPc single-molecule magnets grafted on graphene induces long-range, 2D Ising spin-glass magnetic correlations in the graphene substrate, as evidenced by the analysis of low-temperature magnetoresistance, 1/f noise, and universal conductance fluctuations.
By co-fabricating hybrid gatemon and standard SIS transmon qubits with identical circuit layouts, researchers demonstrate that gatemon relaxation times are limited by an order of magnitude more than theoretical predictions due to an unidentified, temperature-independent, junction-intrinsic dissipation mechanism rather than external circuit losses or quasiparticle effects.
This paper demonstrates a gate-tunable mid-infrared light-emitting diode based on a Te/MoS2 van der Waals heterojunction that emits polarized electroluminescence at 3.5 μm, offering a stable and CMOS-compatible platform for integrated optoelectronics.
This study reveals that intrinsic temporal coherence, rather than just spatial band folding, is the dominant mechanism governing enhanced heat transport in ultrashort-period graphene/hexagonal boron nitride superlattices, offering a falsifiable experimental signature and a new fundamental channel for understanding phonon dynamics.
This paper establishes a general theoretical framework for calculating spin and orbital photocurrents in semiconductors, applying it to the Bernevig-Hughes-Zhang and Luttinger models to characterize optical responses across topological phase transitions and highlight distinct relaxation time dependencies in orbital conductivity.
This paper demonstrates that mismatched CN nanoribbon junctions serve as a tunable platform for engineering Fano resonances in electron transport by using an external gate potential to couple edge states with localized interface states, thereby enabling precise control over the number and line shapes of the resulting interference-driven resonances.
