    Single-crystalline Ti1-xNbxO2 (x = 0.2) films of 40 nm thickness were deposited on SrTiO3 (100) substrates by the pulsed laser deposition (PLD) technique. X-ray diffraction measurement confirmed epitaxial growth of anatase (001) film. The resistivity of Ti 1-xNbxO2 films with x ≥ 0.03 is 2-3 × 10- 4 Ω cm at room temperature. The carrier density of Ti 1-xNbxO2, which is almost proportional to the Nb concentration, can be controlled in a range of 1 × 1019 to 2 × 1021 cm- 3. Optical measurements revealed that internal transmittance in the visible and near-infrared region for films with x = 0.03 was more than 97%. These results demonstrate that the presently developed anatase Ti1-xNbxO2 is one of the promising candidates for the practical TCOs.
