ON THE EFFECTIVE POLARIZATION CHARGES IN THEEXTENSION OF A PIEZOELECTRIC SEMICONDUCTOR FIBER WITH A PN JUNCTION

摘要：

　　We study the extension of a piezoelectric semiconductor (PS) fiber containing a PN junction,focusing on the effective polarization charges which are fundamental to piezotronics.A one-dimensional model derived previously from the macroscopic theory of PSs is used for a linear theoretical and nonlinear numerical analysis by COMSOL.Both homogeneous and heterogeneous junctions are studied.In addition to the built-in electric potential and field as well as Ⅰ-Ⅴ curve,distributed effective polarization charge along the fiber and concentrated effective polarization charge on the junction interface are calculated and examined.
