In Situ characterization of the proton enhanced conductivity of 20nm TiO2 thin-films obtained on the surface of optical fiber
Jacob L. Poole, Paul R. Ohodnicki, Yang Yu +3
We report in situ characterized TiO2 thin-films deposited on optical fiber, having thicknesses in the 20-100nm range, and having enhanced conductivity values of 700S/cm upon intera…
Continuously tuning the refractive indices by restructuring materials on the 20-1000 atoms scale: improving anti-reflection coating designs
Jacob Poole, Aidong Yan, Paul Ohodnicki +1
We demonstrate the capability of block-copolymer templating to tune the refractive indices of functional oxides over a broad range by structuring materials on the 20-1000 atoms sca…
Probing the Hydrogen Enhanced Near-Field Emission of ITO without a Vacuum-Gap
Jacob L. Poole, Yang Yu, Paul R. Ohodnicki
Thermal fluctuations of charged particles, fluctuations akin to Brownian motion, can excite optical surface-states leading to the concept of the thermal near-field, which is a high…
Near-Field Thermal Energy Conversion by Tunneling to a Waveguide
Jacob L. Poole, Paul R. Ohodnicki
Energy is a vital resource and hence there is a continuous strive to improve upon existing technologies and to find new ones that address that basic need. The conversion of thermal…
