Dans une expérience d'impulsion de chaleur dans InSb et Ge, nous avons observé la dispersion des phonons de haute fréquence en utilisant le seuil à 2 Ɗ des jonctions tunnel supraconductrices. La spectrométrie des phonons par mesure du temps de vol a également été appliquée au problème de l'absorption dans le germanium dopé Sb, sous pression.In a heat pulse experiment in InSb and Ge, we have observed the dispersion of high frequency phonons by using the threshold at 2 Ɗ of superconducting tunnel junctions. The phonon spectrometry by measurement of the time of flight has also been applied to the problem of absorption in Sb doped germanium under pressure
