Abstract

The AT-cut is a cut distinctly showing piezoelectrical properties of quartz in practical applications (transducers), but phonon propagation in AT-cut quartz has not yet been investigated in detail. Our aim was to measure the phonon pulses propagating in the direction perpendicular to the AT-cut surfaces, to identify the observed signals on the basis of the theoretical pure ballistic phonon propagation model, to determine if the influence of piezoelectricity on phonon propagation in this direction is detectable and also to observe if our experimental results obtained for a very thin phonon detector depend on the value of the current supplying the detector.
