Self-assembly of Si-based particles for infrared-active metamaterials
Résumé
Si-based particles are synthesized from cyclohexasilane and a silicon coordination complex in supercritical hexane, a synthesis route which produces monodisperse spheres with control over particle size. A solution-based self-assembly method deposits the particles into a close-packed monolayer and optical properties are measured. Mie Theory calculations of single particles are compared to ellipsometry measurements of films of particle assemblies. We demonstrate that a this material, synthesized from an entirely bottom-up approach, has high quality factor resonance in the near-IR with magnetic permeability μ≠ 1.
