Abstract

We have discovered new transparent conducting oxides (TCOs), anatase Ti_1-xM_xO₂ (M=Nb,Ta), in thin film form, Both films with 0.03 ≤ x ≤ 0.06 showed resistivity of 2-3 × 10 ^-4 Ωcm and internal transmittance of ∼95% in the visible light region (40 nm in thickness), at room temperature. These values are comparable to those of typical TCOs, such as In_2-xSn _xO₃ (ITO).
