Abstract
The development of transparent conducting oxides (TCOs) has led to the evolution of a variety of optoelectronic devices. There exists, however, a demand for inexpensive, and efficient materials. Anatase titanium dioxide (TiO2) is such a promising TCO compound. The substitution of group 5 elements for Ti will introduce charge carriers, improving the electrical conductivity of the material. A remaining obstacle for the commercialization of TCOs is that reliable synthesis routes have to be developed that allow mass production at reasonable cost. In this respect solution based processing and deposition is an appealing alternative to standard physical deposition methods that require a high vacuum. However, to our knowledge, reports on solution processing of anatase based TCOs are very scarce. In the current work we present the preparation of group 5 (V, Nb, Ta) doped anatase films by aqueous chemical solution deposition (ACSD). The effect of the dopant on the crystallization, microstructure and electrical properties of the resulting films is examined. To observe the evolution of the film characteristics in real time, in-situ characterization of the crystal structure and sheet resistance is carried out during annealing of these thin films. Nb-doped TiO2 films show the most promising electrical properties. By this work we demonstrate that ACSD in the future may provide a new strategy for TCO production.
