Acoustoelectric effect
A travelling acoustic wave transfers momentum to mobile charge carriers in a semiconductor or metal, producing a direct current or voltage along the direction of propagation.

Relations
- 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
- a travelling longitudinal bulk acoustic wave propagates through a semiconductor, or a travelling surface acoustic wave is coupled to mobile carriers
- net DC Weinreich drag requires directed acoustic momentum; a pure standing wave does not by itself supply the required net momentum
- a gas-borne acoustic wave may couple mechanically into the solid at a gas–solid boundary; an active piezoelectric launcher is an optional implementation, not part of the acoustoelectric effect
Matrix context
D = disequilibrium row · C = coupling family column. A cell reads the state of the atlas for that pair.
