Sentences with phrase «confined phonons»

Not exact matches

Optic phonons, or crystal vibrations that can be excited with infrared light, can also be used to confine light to dimensions much smaller than the wavelength of light, while maintaining record - high efficiencies.

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.

Researchers at the SHINES center showed that they could control phonons by confining them in a field of nanowires.
