N2 - Indium-zinc oxide films (ZnxInyOx+1.5y), with x/y=0.08-12.0, are grown by low-pressure metal-organic chemical vapor deposition using the volatile metal-organic precursors In(TMHD)3 and Zn(TMHD)2 (TMHD=2,2,6,6-tetramethyl-3,5-heptanedionato). Films are smooth (rms roughness=40-50Å) with complex microstructures which vary with composition. The highest conductivity is found at x/y=0.33, with σ=1000S/cm (n-type; carrier density=3.7×1020cm3; mobility=18.6cm2/Vs; dσ/dT2O3, and the absolute transparency rivals or exceeds that of the most transparent conductive oxides. X-ray diffraction, high resolution transmission electron microscopy, microdiffraction, and high resolution energy dispersive X-ray analysis show that such films are composed of a layered ZnkIn2O3+k phase precipitated in a cubic In2O3:Zn matrix.
