Phonons hushed | Nature Nanotechnology


Fashionable data expertise depends totally on the management of two basic particles — the electron and the photon — for carrying electrical energy and lightweight, respectively. However these particles aren’t the one ones when discussing phenomena happening in matter. Usually thought-about to be a nuisance in delicate units, phonons are the bosonic quanta of vibrations in matter, extremely analogous to photons, however tougher to regulate. They could be a channel of disturbance to electrons, photons and different desired vibrational modes. Worse but, phonons can often exist in any respect frequencies as much as THz scale. Writing in Nature Nanotechnology, Florez et al.1 have now reported a major advance in conserving phonons quiet at technologically related frequencies.
