Wurtzite ZnO nano-pyramids grown by evaporation-deposition methods have been characterized using advanced electron microscopy. The basal and pyramidal planes of the nano-pyramids were identified as (0001) polar and 2021 semi-polar surfaces, respectively. The 2021 semi-polar surfaces were further faceted into 1011 semi-polar and 1010 non-polar surfaces. Surface area calculations revealed that approximately 65 % of the total surfaces of the as-grown nanostructures consisted of polar or semi-polar surfaces.
