Metallic gate electrodes are often employed to control the conductivity of graphene based field effect devices. The lack of transparency of such electrodes in many optical applications is a key limiting factor. We demonstrate a working concept of a double layer graphene field effect device that utilizes a thin film of sputtered aluminum nitride as dielectric gate material. For this system, we s...

Polyphenols from green tea were used to electrolessly deposit gold on silk cocoons (SCs) and nanoporous aluminum oxide (AAO) templates. The gold coated cocoons were used as electrodes in supercapacitors and showed a capacitance as high as 254 F g(-1) and a specific power of 2287 W kg(-1). A metal coated AAO template was used for molecular separation.

We have fabricated magnetic tunneling junctions by oxidizing a wedge-shaped aluminum layer to produce junctions with ideal oxidized as well as under and over oxidized junctions on a single wafer. By investigating the capacitance spectra, we are able to study the effects due to interface charge accumulation. The electron–electron interaction among accumulated interface charges leads to a voltage...

Narrow, open-circuited aluminum electrodes can provide controllable, weak reflectivity necessary for many applications such as surface acoustic wave (SAW) tags and dispersive delay lines (DDLs). We show, using finiteand boundary element method (FEM-BEM) based simulations and experiments, that a reflectivity of 0.3% per wavelength can be achieved easily and controlled by varying the electrode wi...

Material properties of copper and aluminum required for the numerical simulation are presented. Electrodes used for the (paper) are depicted.

The tunneling magnetoresistance sTMRd of thin dielectric tunnel barriers that are sandwiched between pairs of ferromagnetic metal thin films is highly sensitive to the barrier layer atomic scale thickness, the uniformity in thickness, and the composition. Widely used AlOx barriers are formed by the oxidation of 1–2 nm thick aluminum layers vapor deposited onto one of the ferromagnetic metal ele...
