| Research Abstract |
Growth mechanism of tungsten trioxide nanorod in tungsten oxide nano structures was studied by real time observation of tungsten oxide nanorod using environmental transmission elec tron microscopy (ETEM). It was cleared that existence of natural oxide layer was needed for growth of tungsten oxide nanorod. Farther, a lot of stacking fault was confirmed in nanorod. Electric property of nanorod was acquired from a nanorod grown in ETEM, and electric properties of bulk and nanorod were compared. Measurement results revealed that nanorod have not semiconductor property bulk have but conductor property.
