Morphology of thin films

After a few hours of A1 substrate storage in ambient air, however, ultrathin PU films tend to de-wet during curing as film thickness is decreased to dpu 100 nm (Fig. 6.6). Ultrathin film samples on Cu after several days of substrate storage in ambient air are subject to de-wetting, too. Films on Au, however, stay

We found that the surface morphology of thin films derived from mixture of TEOS and MTES sols can be controlled by changing molecular weights of siloxane polymers in TEOS and MTES (Takahashi, 1997). We describe the method to produce low refractive index film and discuss the mechanism of formation of different surface morphologies. A new layer to reduce the reflection of the automotive windshield for drivers has been developed by sol-gel method.
