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.

Acoustic field—drives→Acoustoelectric effectdemonstrated
  • 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
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.
Acoustic wave—drives→Acoustoelectric effectdemonstrated
  • 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
