  • Description: We study the extension of a composite fiber of piezoelectric dielectrics and nonpiezoelectric semiconductors. A theoretical analysis is performed using a one-dimensional model. It is shown that mechanical loads cause redistribution of mobile charges in such a composite fiber. Thus, the composite fiber exhibits piezotronic couplings like a homogeneous piezoelectric semiconducting fiber. The couplings are a product property of the composite, enabling the design of piezotronics devices beyond materials with direct piezotronics couplings. The basic behavior of the composite fiber and the effects of various parameters on piezotronic couplings are calculated and examined. It is observed that piezotronic couplings in these fibers are sensitive to material and geometric parameters and can be optimized through design.
