Study on a straight dislocation in an icosahedral quasicrystal with piezoelectric effects

Lianhe LI;Guanting LIU;College of Mathematics Science, Inner Mongolia Normal University;Inner Mongolia Key Laboratory of Nanoscience and Nanotechnology, Inner Mongolia University;  
An electro-elastic analysis is performed on an icosahedral quasicrystal with piezoelectric effects containing a straight dislocation. The closed-form expressions for the elastic and electric fields are obtained using the extended Stroh formalism. The effects of piezoelectric constant on the phonon displacement, phason displacement, and electric potential are discussed in detail.
