Scratching the surface : Atomic force microscopy has been utilized to study the surface of zeolite L (see AFM image of the hexgonal face of a crystal). Correlations between nanometer high features and the structural units have been determined, with the smallest unit protruding from the surface corresponding to a single cancrinite cage. The mechanism by which growth units attach depends on the crystallographic face.
