Highly packed LN-type ZnSnO3 NW arrays are grown on ZnO:Al/Si substrates using a hybrid pulsed laser deposition and solvothermal process. Unique “welding” mechanism structurally joins adjacent ZnSnO3 NWs to form a nearly impervious 20 μm thick nanostructured film that shows high P r of 30 μC/cm2 at a low E c of 25 kV/cm for the first time.
