The apparent morphological difference between ZnO particles with and without an electric field applied during the growth process was elucidated by high-resolution transmission electron microscopy. The ZnO smoke produced immediately below the electric field by burning zinc in a gas mixture of O 2 and Ar, curved towards a negative plate. The typical tetrapod- or needle-shaped ZnO particles were seldom observed in the electric field; spherical particles were predominantly produced. Some of these spherical particles were composed of multiply twinned particles with an antiphase boundary. The growth of these multiply twinned particles was due to an increment in the ionicity in the crystallographic polar direction of ZnO bonding induced by the applied electric field.
