Abstract

Indium-zinc oxide films (Zn_xIn_yO_x+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/dT<0). The optical transmission window of such films is broader than Sn-doped In₂O₃, 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 Zn_kIn₂O_3+k phase precipitated in a cubic In₂O₃:Zn matrix.
