Dual‐Functional Terahertz Manipulation of EuBa2Cu3O7 Superconductors via Cooper Pair Dynamics
Advanced Science, EarlyView.We use a spintronic‐metasurface THz emitter to realize chiral THz generation. Using polarization‐tunable THz pulses, we investigate equilibrium and photoinduced THz responses in a 43 nm thick EuBa2Cu3O7 (EBCO) thin film. The EBCO film achieves 46.81 dB EMI shielding and 113% photoinduced THz modulation with 19.0 ps recovery, enabled by Cooper‐pair ...

Advanced Science, EarlyView.Poly(vinyl alcohol)‐modified liquid‐metal particles form conductive networks through spray‐induced self‐fusion without additional post‐treatment. Spray impact initiates oxide‐shell rupture and electrical contact, while subsequent Marangoni flow and capillary forces promote particle redistribution, neck growth, and network consolidation. This sequential
