Controlled Growth and Field-Emission Properties of Cobalt Oxide Nanowalls

Vertically oriented single‐crystalline Co3O4 nanowalls (see Figure) have been successfully fabricated by directly heating Co foil in air using a hot plate. The morphologies of the Co3O4 nanowalls can be controlled by varying the growth temperature and time. The Co3O4 nanowalls show promising field‐e...

Zusammenfassung:Vertically oriented single‐crystalline Co3O4 nanowalls (see Figure) have been successfully fabricated by directly heating Co foil in air using a hot plate. The morphologies of the Co3O4 nanowalls can be controlled by varying the growth temperature and time. The Co3O4 nanowalls show promising field‐emission performance that is comparable to many other nanomaterials.
