Large‐Area Nanowire Arrays of Molybdenum and Molybdenum Oxides: Synthesis and Field Emission Properties

Well‐aligned nanowire arrays of Mo and its oxides have been synthesized. MoO 2 nanowire arrays are first synthesized by thermal evaporation in a vacuum chamber. With further treatments in the growth chamber, the above nanowire arrays can be turned into MoO 3 nanowire arrays or metallic Mo nanowire arrays (see Figure). The field emission properties of these nanowires are fully investigated.
