EFFECTS OF TWO LOCAL UNIFORM TEMPERATURE CHANGES ON ELECTRICAL BEHAVIORS OF A PIEZOELECTRIC SEMICONDUCTOR FIBER
We theoretically study the behaviors of a piezoelectric semiconductor (PS) fiber in the extensional deformation resulted from the two local thermal loads using the multi-field coupling theory for thermo-piezoelectric semiconductor.With the linearized method,the analytical results are obtained for small temperature changes.For large temperature changes,the linearized method is not valid.In this case,we conduct a nonlinear analysis by COMSOL.The numerical results show that the potential barrier and well produced by the temperature changes through a series of coupling effects could be used to manipulate the forward/reverse currents in the fiber simultaneously.
