Abstract
The calculation of ultrasonic attenuation is discussed for arbitrary frequency and band structure. The results are applied to the cases of a metal with a spherical energy surface and a semimetal with electrons in two "valleys." Possible experimental uses are pointed out. The occurrence of saturation is discussed. The acoustoelectric effect is also treated by similar methods and is seen to be closely related to the attenuation.Keywords
