Sentences with phrase «dielectric material»

A dielectric material is a substance that is an electrical insulator and does not conduct electricity easily. It can store and transmit electrical energy without allowing it to pass through. Full definition
Metal is shown in yellow and orange, dark blue represents dielectric material, and lighter blue denotes the gallium oxide substrate.
In particular, they plan to investigate high - refractive index dielectric materials such as silicon, which, unlike metallic particles, do not suffer from high optical losses.
The results were reported in a recent issue of the journal Advanced Materials in a paper titled «High - performance Polymers Sandwiched with Chemical Vapor Deposited Hexagonal Boron Nitrides as Scalable High - Temperature Dielectric Materials
One day in the lab, the duo was investigating various dielectric materials they could use to fabricate a graphene transistor.
They climbed back into the dish with brooms and scrubbing brushes and carefully swept it clean of what they referred to in a later paper as «white dielectric material,» or what is known more commonly as bird shit.
This research opens new pathways for probing other electromechanical phenomena on the nanoscale that have not been studied before, such as charge trapping and properties of dielectric materials.
Currents are also induced in tissue (as well as any other conducting or dielectric materials) upon exposure to electromagnetic fields.
The technique depends on the use of a dielectric material — which is usually an insulator but that can be polarized in an electric field — to coat the electrode.
Dielectric materials have melting points much higher than metals, and we're now quickly trying to move this technology into the infrared to demonstrate a lighting system.»
The new model uses a dielectric material rather than a metal for the nanoantennas, a change which greatly improves its efficiency and, combined with a new design approach, enables operation over a broad range of wavelengths.
This means that devices using this dielectric material can operate effectively within high humidity contexts such as in a shower or at a beach.
For example, if a dielectric material retains its electrical resistivity after self - healing but not its thermal conductivity, that could put electronics at risk of overheating.
The measurement (false color plot) was the first of its kind in a dielectric material and yielded a time of 150 attoseconds (as), from which the physicists determined that inelastic scattering in the dielectric takes about 370 as.
He flashes a grin and repeats the sequence a few times, explaining: «Fundamentally, our devices are capacitors — two charged parallel plates sandwiching a dielectric material.
By manipulating the structure of aluminum oxide, a dielectric material, researchers were able to improve its optical and mechanical properties.
The metal layer was encased in the dielectric material silicon dioxide, which is commonly used in the semiconductor industry to help route electricity.
