We demonstrate a method for quantitatively probing the local low-frequency dielectric constant of thin insulating films by nanoscale capacitance microscopy. The calibrated capacitance-distance curves are measured on the dielectric film and analyzed by using a tip-sample capacitance model here proposed. App...
Measurement of the Electrical Conductivity and Dielectric Constant without Contacting Electrodes A method is developed whereby electrical conductivity and dielectric constant of semiconducting and dielectric materials without contacting electrodes can ...

The low-frequency dispersion of the complex dielectric constant of a nematic liquid crystal was measured as a function of the thickness of the polyimide alignment layer at 25 and 50℃. The dielectric relaxation strength of the low-frequency dispersion was strongly dependent on the thickness of the...
