Abstract
Self-assembly of ZnO nanoclusters on Si and SiO2/Si surfaces using two different diblock copolymers, polystyrene-acrylic acid and polystyrene-methacrylic acid, is reported in this paper. The conversions of ZnCl2 to ZnO nanoclusters are verified and evaluated using X-ray photoelectron spectroscopy (XPS). The high resolution spectra shows the electron peak at 1021.7 eV for ozone treated sample and the peak at 1021.8 eV for NH4OH treated sample. From AFM image it is found that the size distribution of ZnO is 150 to 250 nm and height distribution is 100 to 130 nm.
