Sentences with phrase «freely moving electrons»

The previously freely moving electrons come to an abrupt halt and the material loses its conducting properties.

Not exact matches

For this to work, the wire's surface must be extremely clean, allowing electrons to move freely and spread along the wire to create a uniform temperature.

When the dust settled in the 1970s, we were left with two kinds of elementary particles: quarks, which group into heavier composites like protons and neutrons; and lighter particles called leptons, like the electron and the neutrino, which can move freely without bunching into heavier combinations.

For this to work, the wire's surface must be extremely clean, allowing electrons to move freely and spread along the wire to create...

This freely moving particle, predicted by many grand theories of the universe, is thought to carry a single quantum of magnetic «charge», rather as an electron carries a single unit of electric charge.

When a rock heats up, some of the electrons inside can move freely.

APDs detect photons because when a photon strikes the top surface of the chip, its energy knocks an electron into an energy level in which it can move around freely.

Unlike the other electrons in the material, which move about freely, the density wave is a periodic, fixed electron phase that seems to compete with and hinder the superconducting phase.

Less evident is the concept that electrons and atoms can move cooperatively to stop the flow of charge — or, in the other extreme, make electrons flow freely without resistance.

The nanomaterial is composed of a single layer of carbon atoms linked in a hexagonal chicken - wire pattern, and all the atoms share a cloud of electrons moving freely about the surface.

Another way is also possible: At a temperature of millions of degrees, the gas in the corona is highly ionized, that is, electrons are stripped off neutral atoms and move freely.

He realized that if the material is well - ordered, like a crystal, with its atoms evenly distributed, the electrons move freely as waves.

Closer to home, I suppose I left out the sun, which of course, itself is mostly plasma, because [the] high - temperature center of the sun is 15 million degrees, and so that is plenty hot enough to separate the electrons and the protons and to make sure that they move around freely inside the center of the sun.

Because of the dense crystal lattice, the electrons could move freely between each of the interactions for only a few ångstrom (10 - 10 meter).

That electron can then move around the crystal freely, and we can get a current.
