|Abstract:||The growth of freestanding, vertically oriented Co3O4 nanowalls by directly heating Co foil on a hot plate in ambient conditions was investigated. The field-emission properties of Co3O4 nanowalls were also investigated. Scanning electron microscopic (SEM) examination revealed a surface covered with a large quantity of nanowall-like morphologies, with most of them perpendicular to the substrate. The results reveal that the Co3O4 nanowalls or other morphologies of Co3O4 nanostructures are useful electron field emitters.|
