Silver Disk Single Crystal

Silver Disk Single Crystal offers exceptional electrical conductivity, high reflectivity, and superior structural coherence in a precisely machined circular form. Its defect-free crystalline structure supports plasmonic, electronic, and optical applications requiring minimal scattering losses. Industries such as nanophotonics, telecommunications, and sensing employ silver single-crystal discs in surface plasmon resonance devices, photonic circuits, and ultra-sensitive detectors. Specific uses include calibration standards for spectroscopy, low-loss resonators, and experimental substrates for quantum plasmonics. Research highlights their use in fabricating nanostructures with enhanced field confinement, enabling breakthroughs in metamaterials and light–matter interaction studies. The disk geometry ensures reproducibility in optical testing and device integration, making these crystals indispensable for advancing precision optics, plasmonics, and electronic innovation.
