Interaction of Sound Vibrations with a Dislocation Chain in a Piezoelectric Crystal

Article

Sound waves in a piezoelectric medium containing a chain of dislocations parallel to each other are investigated. It is demonstrated that interaction between vibrations localized on individual dislocations engenders waves propagating along the chain in the direction perpendicular to dislocations. The spectrum of allowable vibration frequencies consists of bands separated from each other and from the spectrum of volume vibrations. The total number of different independent wave vectors corresponding to frequencies forming a band is equal to the number of independent states of the vibrating dislocation chain and coincides with the number of dislocations contained in it.
