Figure 6

(a) Total microwave energy absorbed by the ITO layer per rotor rotation as the layer conductivity is changed with local absorption patterns (insets). Lower conductivity (σ ~ 103 S/m) ITO-coated glass substrate (b) before microwave reaction and (c) after microwave reaction. Films grown on lower conductivity ITO layers do not exhibit edge patterns and are more uniform than those shown in Fig. 5. Absorbed energy density per rotor rotation for ITO layer pattern sizes of (d) 0.8 cm × 0.8 cm, (e) 0.4 cm x 0.4 cm, and (f) 0.2 cm x 0.2 cm. The energy densities are normalized by 1 J/m3 and the color bars are in dB scale. These results suggest that decreasing the ITO pattern conductivity or size can improve film uniformity.
