Abstract
We propose the use of surface-acoustic-wave attenuation at subkelvin temperatures for the study of localization and mesoscopic phenomena in GaAs/As heterojunctions. Based on the piezoelectric properties of GaAs, we present a diagrammatic interpretation of electronic absorption in terms of coupling of the lattice strain to the electric current.
