This paper presents a scalable, lithography-free method for creating two-dimensional electron gases in SrTiO by using direct atomic layer processing to deposit TiO patterns that guide Al deposition, thereby inducing oxygen vacancies to form conductive channels with high carrier densities and electrostatic tunability without post-growth microfabrication.
This study demonstrates that foundation machine-learned force fields pretrained on broad datasets with incorrect phase energetics can be efficiently corrected for specific correlated materials like NiO through compact target-level fine-tuning, enabling a practical multi-fidelity strategy that prioritizes broad pretraining followed by application-specific adjustment.
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.
Using resonance Raman spectroscopy on hBN-encapsulated monolayer WSe2, the study reveals that asymmetric resonance peaks in the optical phonon mode arise from third-order scattering that couples bright excitons to momentum-dark excitons approximately 45–55 meV lower in energy, thereby providing a microscopic framework for understanding the material's efficient bright-to-dark exciton coupling and anomalously bright emission.
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 paper presents a novel thermoelastic harvester utilizing NiTi shape-memory alloys with three key design innovations that achieve a record-breaking power density of 366 mW/cm³, outperforming existing thermoelectric, thermomagnetic, and pyroelectric generators for low-grade waste heat recovery below 100°C.
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 study demonstrates that applying ISO 21920-2 feature characterization to turning surface profiles, specifically using the groove-level mean maximum absolute gradient (), enables robust and physically interpretable estimation of tool wear by isolating deterministic wear-induced changes from stochastic surface noise.
The study identifies TlYbSe as a prime candidate for a field-tunable triangular quantum spin liquid, characterized by a disordered ground state down to 20 mK, a spin-glass transition at 30 mK attributed to free spins, and a robust linear heat capacity at low temperatures explained by the interplay of spinons and thermally excited gauge flux excitations.
This paper extends the EPW package to calculate electron-phonon coupling in magnetic materials using the local spin density approximation, revealing through validation on iron and nickel that electron-phonon scattering dominates resistivity in iron but accounts for less than one-third of it in nickel, highlighting fundamental differences in their transport properties.
