Abstract :
We have investigated the effect of piezoelectric charges on the surface depletion region of ZnO NWs. By considering an inner region with a non-negligible density of free carriers and a depleted region at surface of the ZnO NWs and by solving the Poisson equation in the depleted region, the surface depletion width is derived. Thus, the effect of piezoelectric charges on the surface depletion region has been investigated.
