WE4.4 - PROBING THE INFLUENCE OF DIELECTRIC ENVIRONMENT UPON VOLUME-CONFINED HYPERBOLIC POLARITONS
Abstract
Abstract
We employ nano-scale imaging and spectroscopy techniques to elucidate polariton characteristics as a function of the complex refractive index of the substrate. Although higher-order polariton modes exhibit wavelengths weakly sensitive to the environment, the principal mode strongly depends on the substrate dielectric constant
WE4.5 - NANOSCALE IMAGING AND SPECTROSCOPY OF CHARGE CARRIER DISTRIBUTION IN DOPED SILICON NANOWIRES BY THZ NANOSCOPY
Abstract
Abstract
We report on nanoscale carrier distribution and spectroscopy of doped silicon nanowires using terahertz (THz) time-domain nano-spectroscopy technique. We demonstrate the capability of THz-nanoscopy for probing and quantification of the order of doping levels in a single nanowire containing heterogeneously doped sections.
