Transparent conducting oxides (TCOs) are truly unique materials that, as thin conducting or
semiconducting films, find many applications of great importance in electronic
circuitry/display applications, in solar electricity generation, in energy conservation, and in
high-speed optical telecommunication [1]. However, it is not clear that present generation
TCO materials (e.g., tin-doped indium oxide, ITO, or others) will meet the stringent
performance and cost requirements for next-generation opto-electronic technologies, nor have
all the necessary properties for many new applications. This lecture focuses on the scientific
aspects of designing, growing, characterizing, understanding, manipulating, and
implementing next-generation transparent conducting oxide thin films in some very
unconventional roles. This includes their implementation in the following areas: a) high-
performance transparent, flexible electronic logic circuitry as semiconductors, gate
dielectrics, and/or conductors [1-4], b) interfacial layers and electrodes in third-generation
bulk-heterojunction solar cells [5,6] ; c) 2D gate-tunable heterojunctions with unusual
electronic function [7,8], and d) transparent conducting electro-optic modulator components
in high-speed optical signal processing systems [9].
