Abstract

ZnO nanometer particles were synthesized by depositing ZnO colloidal suspensions onto the substrate of Highly Oriented Pyrolytic Graphite (HOPG). The isolated particles and their aggregation phase were directly imaged by Atomic Force Microscopy (AFM). High-resolution AFM images have been used to measure the diameter of individual particles, and large area images revealed that these ZnO particles on graphite surface form netlike aggregation. Experimental results also indicated that dispersive particles on a flat area are very mobile and easy to be pushed around during scanning due to the their weak adsorption on the substrate and tip-particle interactions.
