Resumop-Type Sb-doped ZnO nanobranched films are synthesized by an innovative approach: sputtered nanobranched Zn films are impregnated in an Sb-based solution and thermally treated to simultaneously oxidize Zn and insert the Sb dopant in the wurtzite structure. Sb doping of ZnO results in a rise of the piezoelectric voltage generation and, for the first time, ferroelectric properties and a ferroelectric-driven photovoltaic effect.
