    The transparent conductor Nb12O29 was found to exhibit high-temperature stability superior to that of conventional transparent conducting oxides (TCOs). The Nb12O29 thin film was fabricated on a glass substrate, followed by annealing at 1000 C in vacuum, and a high conductivity of 3.0 × 102 Ω- 1 cm - 1 at room temperature was maintained even after vacuum annealing at 800 C. Although the conductivity of the Nb12O29 film was decreased by annealing at 300 C in air, the initial high conductivity was recovered upon subsequent vacuum annealing. These properties indicate that Nb12O29 is a promising material applicable in cases where conventional TCOs cannot be used.
