Abstract

AFM has been applied for studying morphology and size distribution ofnanometer-sized particles adsorbed on flat surfaces. In order to optimize imaging of these ultrafine particles different substrates were evaluated with respect to their roughness and stability under tile influence of the sensing tip. Moreover, a method for calculating particle volumes from the three-dimensional AFM data is described. This greatly enhances the information content of AFM images, because a large numberof particles in the raw data call be evaluated automatically in orderto derive information on size distribution or surface coverage. This evaluation method has also been applied successfully to quantitativelydescribe changes on particles induced by different humidity of the surrounding atmosphere.
