摘要: The transport properties of a d-electron-based transparent conducting oxide, Nb-doped anatase Ti1−xNbxO2, were investigated as function the Nb content x. From optical resistivity spectra, static effective mass was evaluated to be ∼0.4m0 in low-carrier-concentration (ne) regime, which is approximately same those conventional oxides (TCOs), and two orders magnitude smaller than that reported for rutile TiO2. Hall mobility at room temperature, maximized around x=0.01 (ne∼1021cm−3), found mainly dominated by phonon scattering unlike other TCOs.
