Dielectric

Increasing the dielectric constant of the gate dielectric allows a thicker layer while maintaining a high capacitance (capacitance is proportional to dielectric constant and inversely proportional to dielectric thickness).

Dielectric dispersion In physics, dielectric dispersion is the dependence of the permittivity of a dielectric material on the frequency of an applied electric field.

The generic term for the dielectric is gate dielectric since the dielectric lies directly below the gate electrode and above the channel of the MOSFET.

The research team developed microscale, stepwise structures containing an array of metal/dielectric/metal Fabry-Pérot (MDMFP) cavity resonators to act as color filters with varied dielectric thicknesses.

A dielectric mirror used in lasers For scientific optical work, dielectric mirrors are often used.

All else equal, a higher dielectric thickness reduces the quantum tunneling current through the dielectric between the gate and the channel.

Dielectric dispersion is very important for the applications of dielectric materials and for the analysis of polarization systems.

Dielectric films tend to exhibit greater dielectric strength than thicker samples of the same material.

Dielectric loss is caused when the insulating material inside the transmission line absorbs energy from the alternating electric field and converts it to heat (see dielectric heating ).

Dielectric polarization Basic atomic model Electric field interaction with an atom under the classical dielectric model.

In addition, a high vacuum can also be a useful, nearly lossless dielectric even though its relative dielectric constant is only unity.

Since the dielectric constant, dielectric loss tangent value, and volume resistivity are high, the corona resistance is not very good, and it is generally suitable for medium or low voltage and low frequency insulation materials.

The dielectric losses increase in this order: Ideal dielectric (no loss), vacuum, air, polytetrafluoroethylene (PTFE), polyethylene foam, and solid polyethylene.

Theremin recalled he made the dielectric device first followed by the radio alarm, although Glinsky (p. 23) writes Theremin made the alarm first and then the dielectric device.

The strong polarity of water is indicated by its high dielectric constant of 88 (at 0 °C). citation Solvents with a dielectric constant of less than 15 are generally considered to be nonpolar.

While many cables have a solid dielectric, many others have a foam dielectric that contains as much air or other gas as possible to reduce the losses by allowing the use of a larger diameter center conductor.

Dielectric refers to a liquid that does not conduct electricity the way water does.

As with most lubricants, dielectric grease is made from multiple components, including a silicone base and a thickener.

Each layer of a chip’s wiring begins with a thin film of dielectric material, which is etched to create channels that are filled with copper.

Hydrogen bonds are responsible for all of the unusual properties of water, which include high specific and latent heat, high viscosity, high surface tension, high solvent ability, high dielectric constant and more.
