Sentences with phrase «from phonons»

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.

Systematic analysis is performed based on the study of the contribution from phonon branches, comparison among the mode level phonon group velocity and lifetime, the detailed process and channels of phonon — phonon scattering, and phonon anharmonicity with potential energy well.

U.S. Naval Research Laboratory (NRL) scientists, in collaboration with researchers from the University of Manchester, U.K.; Imperial College, London; University of California San Diego; and the National Institute of Material Science (NIMS), Japan, have demonstrated that confined surface phonon polaritons within hexagonal boron nitride (hBN) exhibit unique metamaterial properties that enable novel nanoscale optical devices for use in optical communications, super-resolution imaging, and improved infrared cameras and detectors.

This illustration shows the emission of phonons (sound waves) from a nanometer scale waveguide, as optical waves flow through it.

the former calculated from the number and frequency of the ion's phonons (vibrational mechanical energy)

Called the quantum phonon, this subatomic acoustical wave can be detected only by intricate instruments that distinguish pure silence from its smallest possible deviation.

They took a first step in 2010, when Cleland, then at the University of California, Santa Barbara (UCSB), siphoned every phonon out of an oscillating cantilever etched from aluminum nitride, leaving it in its least energetic quantum ground state.

That's when the phonon is transported from the generator to the detector.

When they modeled heat flow between two sodium chloride lattices, the researchers found that heat flowed from one lattice to the other via phonon tunneling, at gaps of one nanometer and smaller.

However, the new research shows that phonons can reach across a gap as small as a nanometer, «tunneling» from one material to another to enhance heat transport.

We found that, different from graphene and ML BN, the phonon — phonon scattering selection rule in 2D GaN is slightly broken by the lowered symmetry due to the large difference in the atomic radius and mass between Ga and N atoms.

This is particularly true for electrons and phonons transport in semiconductors where a lot of efforts were done to synthetize nanostructures with properties radically different from their bulk counterpart.

Resulting from the special sp orbital hybridization mediated by the Ga - d orbital in ML GaN, the strongly polarized Ga — N bond, localized charge density, and its inhomogeneous distribution induce large phonon anharmonicity and lead to the intrinsic low κ of ML GaN.

She investigated and helped explain the fundamental interactions between electrons and phonons in nanostructures, and by the year 2000 was able to isolate the Raman spectra from individual nanotubes.

The lyrics tell a story of how researchers at MIT's S3TEC center want to harness thermal energy for electricity generation, but must find a way to «stop the phonons from giving away...

Choose from 20 unique characters, from series veterans like Hyde, Merkava, and Linne to one of the four newly - introduced characters (Phonon, Mika, Wagner and Enkidu) and unleash their power!

So energy does indeed flow from hot objects to cold object AND from cold objects to warm objects (via those photons, phonons, collisions...).
