quantum dot

quantum dot
A minuscule crystal of semiconductor material composed of various compounds of chemicals such as cadmium, zinc, tellurium, selenium and sulfur. Less than 500 nanometers in size, these "nanoparticles" react to electricity or light by emitting their own light across the visible range of wavelengths from 470 to 730 nm.

The applications for quantum dots include solid state lighting, with the potential to render incandescent bulbs obsolete in the future and the ability to paint lighting systems onto materials. They are used in the manufacture of medical sensors and solar cells. Thin film deposits of quantum dots on solar cell substrates substantially increase their voltage output by fluorescing the light before it is captured. See QuantumFilm.
quantum dot [‚kwänt·əm ′dät]
(electronics)
A quantized electronic structure in which electrons are confined with respect to motion in all three dimensions.

(physics)quantum dot - (Or "single-electron transistor") A location capable of containing a single electrical charge; i.e., a single electron of Coulomb charge. Physically, quantum dots are nanometer-size semiconductor structures in which the presence or absence of a quantum electron can be used to store information.

See also: quantum cell, quantum cell wire, quantum-dot cellular automata.

citizen is not eligible for a marital deduction unless the transfer is made to a qualified domestic trust, which is generally referred to as a QDOT.
It also provides an opportunity to have a less complicated estate plan, by possibly eliminating the need for a QDOT for a non-U.
The estate tax as calculated under the QDOT rules generally is deferred until distributions are made from the trust or upon the death of the surviving spouse.
