Acoustic wave —drives→ Acoustoelectric effect

Conditions

• 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

Constitutive relation

|j_AE| = μ |Γ| I_s / v_s

I_s is positive along the acoustic wavevector and Γ > 0 is the intensity attenuation coefficient due to the carriers; momentum transfer is along propagation, so electron drift gives conventional current opposite to propagation while hole current is along it — the magnitude form keeps the carrier sign out of μ.
