Broadband Enhancement of Near-Field Radiative Heat Transfer via Intrinsic Carrier–Lattice Interactions

This study experimentally demonstrates that intrinsic carrier-lattice interactions in heavily doped gallium arsenide significantly enhance near-field radiative heat transfer by more than doubling the flux compared to undoped samples through a coupled plasmonic-phononic response, offering a new pathway for tunable thermal management in nanoelectronics.

Hydrogen-Helium-coupled deformation of core-shell cavities in iron-based fusion structural materials

This study establishes an experimentally constrained multiscale framework revealing that hydrogen-helium coupling in iron-based fusion materials drives cavity-mediated deformation through a complementary mechanism where helium-induced internal pressurization sustains stress concentration while interfacial hydrogen facilitates defect activation by lowering interstitial formation energies.

Development of a voltage-divider based probe method for sheet resistance measurement of copper foils and thin films

This paper presents a voltage-divider-based probe method for measuring the sheet resistance of copper foils and thin films, demonstrating its effectiveness in providing reproducible results for micrometer-thick samples and enabling measurements of nanometer-thick films where conventional four-point probe techniques fail.

Co-evaporated compositionally modulated interfaces in perovskite/Si tandems

This study demonstrates that solvent-free co-evaporation enables the creation of a vertically compositional 2D/3D interface in perovskite/silicon tandem solar cells, achieving a record 30.93% efficiency and exceptional long-term stability by eliminating bulky organic cations while ensuring coherent crystal connectivity and suppressing defect formation.

Probe-Aware Small-Data Inverse Design and Experimental Benchmarking of Free-Space Second-Harmonic Generation in Au/ITO Hybrid Nanopillars

This paper presents a probe-aware small-data inverse design workflow that successfully identifies and experimentally validates an optimized Au/ITO hybrid nanopillar geometry for enhanced free-space second-harmonic generation, attributing the performance boost to localized plasmonic and interface fields rather than epsilon-near-zero effects.
