Localized Ion Irradiation Enables Topography‐Free High‐Tc Superconducting Metamaterials
Advanced Optical Materials, EarlyView.A topography‐free oxygen ion‐irradiation strategy is demonstrated for patterning superconducting YBCO terahertz metamaterials without physical material removal. The approach preserves film integrity while enabling large spectral tunability, ultrafast optical modulation, and dual‐band resonance control, providing a scalable platform for low‐loss ...

Near‐Field Nanoimaging of Programmable Phase Transitions in Ga+‐Irradiated VO2
Advanced Optical Materials, EarlyView.Focused Ga+ ion irradiation locally reprograms the insulator‐to‐metal transition in VO2 thin films. Infrared and terahertz near‐field nanoimaging reveals that low irradiation doses localize the resistive‐switching filament within the defect region, while high doses suppress switching there and redirect the filament into pristine VO2.
