| Popis: | A piezoelectric semiconducting ZnO nanowire under the action of a torque is analyzed. The shear stresses in the cross-section are acquired from classical elasticity. Based on the obtained results, the electric potential, the electric field and the electric displacements can be found from the Gauss law in electrostatics together with the conservation of charge. Numerical results show that the torque deformation produces large effect on the electric displacements but little contribution to the electric potential. The study is helpful to development of piezoelectric semiconductor devices. |
