                      flash sintering and the formation of nanostructures in
                      undoped ZnO. The combination of high electric field and low
                      current density (1 and 2 A/cm2) results in the formation of
                      hot spots and fracture as well as ZnO nanostructures in the
                      vicinity of the hot spots. Such phenomena were not observed
                      in the case of higher current density limit of 3 A/cm2. A
                      detailed microscopy analysis revealed that the growth of
                      nanostructures initiated from liquid phase regions at the
                      grain boundaries and within the grains},
