Sentences with phrase «carrying phonons»

Not exact matches

Phonons thus can't carry heat across a porous material as efficiently, giving the material a low thermal conductivity, which turns out to increase the efficiency of heat - to - electricity conversion.

If even a small amount of energy from phonons (the sound units that carry the energy through the germanium or silicon, much as photons are the units of light) hit the detector, it can be enough to make the device lose superconductivity and register a potential dark matter event through a device called a superconducting quantum interference device, or SQUID.

Heat travels through a material via phonons, quantized units of vibration that act as heat - carrying particles.

And in the same way that white light is actually composed of many different colors of light, these thermal phonons are made up of many different frequencies — each carrying varying amounts of heat.

A phonon's mean free path is the distance a phonon can carry heat before colliding with another particle; the longer a phonon's mean free path, the better it is able to carry, or conduct, heat.

For example, if an engineer desires a material with certain thermal properties, the mean free path distribution could serve as a blueprint to design specific «scattering centers» within the material — locations that prompt phonon collisions, in turn scattering heat propagation, leading to reduced heat carrying ability.

Normally these waves, or phonons, are only able to carry heat within, and not between, materials.

The study also reveals a dramatic reduction of the number of phonons carrying heat, as a result of structural complexity, allowing a simple and general...
