Thermoplastic modification of polycrystalline copper surface microstructure by nonmelting nanosecond laser pulses
Mechanisms of surface relief formation on bulk polycrystalline oxygen-free copper samples under single and multiple UV nanosecond laser pulses (355 nm, 10 ns) in air are investigated. The laser spot s...
Decoupling nonlinear programmability from resonance tuning in a spectrally stable graphene–GaN terahertz nanocavity
Electrically tunable graphene metasurfaces commonly rely on Fermi-level modulation to reshape plasmonic resonances, a process that inherently couples amplitude control to undesirable resonance-frequen...
Lanthanide ion electronic structure controls magnetic excitations in topological quantum ferrimagnets LnMn6Sn6 (Ln = Tb, Dy, Ho)
The LnMn6Sn6 family of topological magnets is a promising platform for next-generation spintronic and magnonic technologies. However, the influence of the lanthanide ion (Ln3+) on the excited-state sp...
Revealing nanoscale motion under photon limited coherent x-ray diffraction
Time-resolved coherent x-ray diffraction provides a powerful probe of nanoscale dynamics. Yet its extension beyond static imaging is constrained by photon exposure, background scattering, and instabil...
Interfacial structural modification in Cu/low- <i>k</i> interconnects revealed by atomic force microscopy infrared spectroscopy
Process-induced modification confined to the immediate vicinity of Cu/low-k interfaces is a key issue in advanced interconnects, yet direct vibrational-band-specific characterization of this region on...
Suppressing anisotropy in nanostructured Fe/Ni superlattices with monolayer periodicity
We described here the growth of carefully engineered Fe/Ni(100) superlattices with monolayer periodicity (i.e., Fe50Ni50) on a Cu(100) crystalline substrate, nanostructured to 70 × 40 nm islands. The...
Enhancing optical confinement in hybrid surface plasmonic nanocavities via external mode coupling near avoided resonance crossings
Plasmonic devices have been intensively studied in the past few decades. However, the substantial intrinsic ohmic losses imposed by noble metals highly limited further applications of such devices. He...

Terahertz time-domain ellipsometry was used to examine the electrical properties of low-dose implanted/annealed silicon carbide (SiC) subjected to different implantation and annealing temperatures. P-...
Pronounced bias-enhanced photocurrent with strong polarization sensitivity in 1T-TiSe2-based photodetectors
We report a 1T-TiSe2-based photodetector with pronounced polarization sensitivity and broadband visible-light photoresponse under low-bias conditions. Using a combined density-functional theory and no...
Growth window and wurtzite phase stability of molecular-beam-epitaxial ScInN thin films with composition-dependent photoluminescence
We establish the growth window and wurtzite phase stability of plasma-assisted molecular-beam-epitaxial ScInN thin films over a broad composition range. Lower growth temperatures suppress rock salt ph...
Oxygen concentration effect on the behavior of point defects in YBa2Cu3O6.5−7: A first-principles study
Understanding defect behavior in high-temperature superconducting magnet materials, such as yttrium barium copper oxide (YBa2Cu3O7−δ), is vital for predicting changes in their superconducting properti...
