This paper presents the development of room-temperature magnetic p-n junctions combining p-type amorphous magnetic semiconductors and n-type silicon, which function as charge-and-spin diodes exhibiting giant magnetic enhancement and significantly increased magnetic moments through the manipulation of spin-polarized space charges.
This paper presents a numerical investigation of the Lieb lattice's electronic and optical properties, revealing the existence of stable, long-lifetime plasmon modes with unusual dispersions and static screening characteristics that resemble graphene rather than pseudospin-1 materials.
This study employs first-principles calculations to propose that the experimentally observed N-line series in silicon arises from complex defects involving carbon, nitrogen, self-interstitials, and oxygen, identifying them as isoelectronic spin-doublet qubits suitable for quantum technologies near telecommunication bands.
This paper presents a unified machine learning framework to systematically compare the impact of different thermodynamic structures—such as dissipation potentials, generalized standard materials, and metriplectic systems—on the learnability, stability, and generalization of data-driven constitutive models for complex inelastic materials.
This study demonstrates that a tungsten multicomponent alloy achieves extraordinary radiation resistance by engineering a fragmented vacancy diffusion network with heterogeneous migration barriers, which kinetically traps defects and prevents cluster growth even under extreme irradiation doses.
Replacing divalent Sn with trivalent In in the kagome ferromagnet Co3Sn2S2 to form Co3SnInS2 suppresses its long-range ferromagnetism and topological transport features, driving the system from a half-metallic state into a semiconducting state with predominantly antiferromagnetic correlations and a significantly reduced anomalous Hall effect.
This paper demonstrates that uniform optical illumination can induce a spatially non-uniform, symmetry-allowed static charge redistribution within moiré superlattices, enabling all-optical control of electrostatic potentials through the unique intra-supercell degrees of freedom.
Using a non-perturbative numerical approach, this study maps the finite-temperature phase diagram of a strongly correlated -wave altermagnet, revealing that altermagnetism-induced geometric frustration stabilizes a correlated magnetic metal and enhances magnetic transition scales across the Mott insulator-metal transition.

This paper presents a capacitively coupled GaAs p-i-n/substrate photodetector featuring a novel multi-step annealing process for Cr/Au ohmic contacts on lightly doped n-GaAs and a leakage-reducing biasing scheme, demonstrating the ability to detect high-energy X-ray pulses with approximately 10^6 electrons per pulse as a precursor to 3D SAM APD detectors.
This study introduces a novel Ni2+-Cr3+ synergistic platform that achieves record-high, fully decoupled simultaneous optical sensing of pressure and temperature under extreme conditions by leveraging time-gated dual-ion lifetime and single-ion luminescence strategies to eliminate cross-sensitivity.
This paper introduces HERB, a unified thermomechanically consistent framework driven by the Rice-Beltz concept that integrates hydrogen transport, dislocation emission, and void growth to reconcile multiple hydrogen embrittlement mechanisms (HEDE, HELP, NVC, and HESIV) within a single multiscale model.
This paper reports the successful growth of high-quality CrSb single crystals via the self-flux method and characterizes their superior thermodynamic and transport properties, including a high residual resistivity ratio, significant positive magnetoresistance, and specific heat features indicative of weak electronic correlations and altermagnetic order, thereby establishing CrSb as a promising candidate for room-temperature magnonic and spintronic applications.
This study utilizes time-of-flight photoemission electron spectroscopy to demonstrate that anisotropic conductivity in distinct diamond- and triangular-shaped sectors of rubrene microcrystals enables dual-wavelength control of charge accumulation, allowing for the creation of spatially and temporally manipulable built-in charge landscapes.
