    The transport properties of a d -electron-based transparent conducting oxide, Nb-doped anatase Ti1-x Nbx O2, were investigated as a function of the Nb content x. From optical resistivity spectra, the static effective mass was evaluated to be ∼0.4 m0 in the low-carrier-concentration (ne) regime, which is approximately the same as those of conventional transparent conducting oxides (TCOs), and two orders of magnitude smaller than that reported for rutile Ti O2. The Hall mobility at room temperature, which is maximized at around x=0.01 (ne ∼ 1021 cm-3), was found to be mainly dominated by optical phonon scattering unlike that of other TCOs.
