Atomic Force Microscope Study of Glass Surfaces After Etching with HF and Alumina Polish

摘要

The generally adopted method of surface patterning on glass is by etching in hydrofluoric acid. Similarly, for surface polishing, nanometer sized alumina powder is generally used. It is therefore important to understand the effect of these processes on the surface topography. An attempt is made here to use the atomic force microscopy to map the specimen surfaces which had been subjected to the above processes under controlled conditions.
