Abstract :
Phonons have been generated and detected at 70 kMcps using piezoelectric surface excitation in single-crystal quartz. Echoes are observed from multiple reflections of acoustic waves in a quartz rod excited by a microwave pulse. The temperature dependence of the relative attenuation of several acoustic modes has been measured from 4.2/spl deg/ to 25/spl deg/K. Previously, experiments using the surface excitation of acoustic waves in solids have been carried out up to 24 kMcps.
