This study reveals that the large, bias-tunable magnetoresistance in CrSBr-based van der Waals heterostructures arises from spin-dependent interlayer hybridization that linearly modulates the barrier band-edge offset with magnetization angle, rather than from electrode spin polarization as described by the Jullière model.
This study demonstrates that layer number serves as a critical tuning parameter in rhombohedral graphene multilayers, revealing an unconventional dependence of symmetry-breaking phase transitions on thickness and the emergence of decoupled, gate-controllable surface-state transport in hexalayer systems.
This study utilizes first-principles and tight-binding simulations to demonstrate that a SiO substrate induces a complex, anisotropic spin texture in graphene—ranging from Rashba-type helical structures to symmetry-broken configurations—resulting in a spin lifetime anisotropy between 0.5 and 1 that aligns with experimental observations and exceeds the predictions of standard Rashba models.
This study demonstrates that planar Ag/MAPbI thin single-crystal devices exhibit ultra-low dark currents and thermally activated transport, while light illumination induces optically tunable threshold switching and polarity-dependent hysteresis driven by coupled interfacial and ionic processes at the Ag/perovskite contacts.
This study demonstrates that the spin spiral state in multiferroic NiI2 thin films undergoes a dimensional crossover driven by enhanced interlayer exchange energy as thickness increases, while local strain from film wrinkles can deflect the spin spiral wavevector, establishing both thickness and strain as effective tuning methods for engineering non-collinear magnetism and electric polarization in van der Waals multiferroics.
This study demonstrates that intrinsic excitonic transitions in transition metal dichalcogenide monolayers, particularly the out-of-plane dipoles of dark excitons, can generate directional light emission at large angles without requiring external nanostructuring, offering a new platform for compact nanoscale photonic routing.
This paper theoretically proposes two distinct routes—staggered potential and perpendicular magnetic field—to transform a topologically trivial altermagnetic state into quantized anomalous Hall states with Chern numbers and , respectively, characterized by specific gap closings and chiral edge states.
This lecture notes review the fundamental principles of ferromagnetism in ultrathin 3d transition-metal films, highlighting how vertical quantum confinement leads to two-dimensional spin ensembles with unique ground state properties, critical behavior governed by the 2D Ising universality class, and complex phase transitions involving spin reorientation and topological stripe excitations.
This theoretical study demonstrates that in 1.6 nm-thick silicon nanosheets, realistic phonon confinement boundary conditions significantly reduce room-temperature mobility and lower the high-field saturated velocity, while remote-phonon scattering from high-kappa gate stacks has a negligible negative impact on low-field mobility and actually enhances saturated velocity by cooling electrons.
This paper demonstrates that a magnetic vortex induces an emergent Ellis wormhole geometry for electrons, producing distinct experimental signatures such as universal deflection patterns and parity-dependent Aharonov-Bohm responses that can be observed in quantum materials and designer honeycomb lattices.
