This is substantiated by the observation of the 29-cm -1 absorption line of O 16 impurities in silicon, so far only known from infrared spectra.eninfo:eu-repo/semantics/openAccessSupraleiter , Phononenemission530Evidence for 870 GHz phonon emission from superconducting Al tunnel diodes through resonant scattering by oxygen in siliconarticle2014-09-11
