Graphene-based Thin Film Supercapacitor with Graphene Oxide as Dielectric Spacer
Thin film supercapacitors are produced by using electrochemically exfoliated graphene (G) and wet-chemically produced graphene oxide (GO). Either G/GO/G stacked film or sole GO film are sandwiched by two Au films to make devices, where GO is the dielectric spacer. The addition of graphene film for charge storage can increase the capacitance about two times, compared to the simple Au electrode. ...
متن کاملThickness and dielectric constant determination of thin dielectric layers
We derive a method for the determination of the dielectric constant and thickness of a thin dielectric layer, deposited on top of a thick dielectric layer which is in turn present on a metal film. Reflection of pand s-polarlzed light from the metal layer yields minima for certain angles of incidence where the light is absorbed by the metal. The thin dielectric layer causes shifts in the angles ...

متن کاملTHE THIN FILM CAPACITORS WITH AlN DIELECTRIC
The work is focused on thin film technologies especially on sputtering of dielectric thin film layers. The set of thin film capacitors was created on silica glass substrate. Aluminum electrodes of separated capacitors are deposited by method of vacuum evaporation. The AlN dielectric layer was prepared by reactive high frequency sputtering from aluminum target in nitrogen atmosphere. Dielectric ...
متن کاملAnomalous quantum transport in a thin film.
We present a numerical study of electron transport in a thin film of varying disorder strength with the distance from its surface. A simple tight-binding model is used to describe the system, in which the film is attached to two metallic electrodes and the coupling of this film to the electrodes is illustrated by the Newns-Anderson chemisorption theory. Quite interestingly we observe that, in t...
