The acoustic second harmonic generation in transversely magnetised nondegenerate piezoelectric semiconductors in the presence of an electrostatic field in the direction of the wave propagation is studied theoretically. Even in trap‐free semiconductors the electrostatic field and the carrier concentration inside the sample are taken as nonuniform. It is found that the relative flux of second harmonic gets enhanced due to this nonuniformity; whereas application of magnetostatic field reduces it. Numerical estimations are made for n‐CdS at room temperature.
