This contribution reports the in situ growth of transparent, conducting GaxIn2-xO3 and ZnkIn2Ok+3 films by MOCVD (metal-organic chemical vapor deposition) techniques using In(dpm)3, Ga(dpm)3, and Zn(dpm)2 (dpm = dipivaloylmethanate) as volatile precursors. In the former series, film microstructure in the x = 0.4 - 1.0 range is predominantly cubic with 25 °C electrical conductivities as high as 1300 S/cm (n-type; carrier density = 1.2×1020 cm-3, mobility = 68 cm2/Vs) and optical transparency in the visible region greater than that of ITO. In the latter series, films in the composition range k = 0.16 - 3.60 were studied; the microstructural systematics are rather complex. Electrical conductivities (25 °C) as high as 1000 S/cm (n-type; carrier density = 3.7×1020 cm-3, mobility = 18.6 cm2/Vs) for k = 0.66 were measured. The optical transparency window is significantly broader than that of ITO.
