Acoustic field → Electrical work

Matrix context

D = disequilibrium row · C = coupling family column. A cell reads the state of the atlas for that pair.

   • a travelling acoustic wave in a piezoelectric semiconductor (CdS, GaAs) or a metal; the dc current follows the wave's direction and is proportional to the absorbed acoustic power

   solid

   Parmenter 1953 is the theoretical prediction; Weinreich and White 1957 the one experimental observation recorded so far, so the atlas threshold for established (two independent groups, or a review or book) is not yet met.
