Abstract

Highly ordered ZnO crystals of 0.15 μm width and 0.5 μm length were grown on silicon wafers coated with a monolayer of SiCl₃(CH ₂)₁₁-O-C₆H₅ molecules. Various techniques (contact angle measurements, ellipsometry, ATR-FTIR) were employed for determining the quality of the monolayer coating. In addition, the bare and silane-coated Si wafers were studied by X-ray reflectivity (XR) and grazing-incidence diffraction (GID) using synchrotron radiation. The results obtained point to a possible relationship between the organization of the self-assembled monolayer (SAM) coating, the dipole moment of the headgroup, and the orientation of the ZnO crystals.
