Abstract
The influences of semiconductive effect on the wave motion and potential output of piezoelectric semiconductor nanoplate were studied. The dispersion curves for different plate thicknesses were obtained, along with detailed distributions of displacements, electric potential, and concentrations of holes and electrons. Results show semiconductive property will result in size-dependent acoustic energy loss. Meanwhile, new size-dependent wave modes appear whose predominant energy is caused by holes and electrons with negligible mechanical energy. On the other hand, the semiconductive property will also reduce potential output significantly, and the detailed mechanical and electrical influence factors on piezoelectric potential are studied for the improvement of the potential output. This work studied a steady state process of wave propagating in nanoplate involving both electron and hole using a fully coupled constitutive equation, which is a more realistic picture for revealing intrinsic characteristics of semiconductive piezoelectric materials.343
