Abstract :
There is an expanding interest in the development of new transparent conducting oxides (TCOs) for a host of applications including photovoltaics, flat panel displays, and low-e and electrochromic windows. In this paper, we discuss the application of compositional spread combinatorial techniques for the initial characterization of the ZnO-SnO2 TCO tie line. Local maxima in the composition dependence of the conductivity were found for Zn/Sn - 2:1 (Zn2SnO4) and Zn/Sn - 1:1 (ZnSnO3). Interesting compositions were further explored by pulsed laser deposition.
