Abstract

In scanning probe microscopy (SPM) imaging of the structure of the tip apex at a mesoscopic scale is extremely important. The present paper offers a simple way for estimating the shape of SPM tips. A standard sample consisting of a close packed monolayer of small polystyrene latex balls is used to characterise the tip shape. The image formation process is simulated by a matrix “convolution” method and the dependence of the SPM image on the tip shape is studied by calculating images of the test sample. Real pictures taken on the same test sample were used to calculate the shape of the tip utilising the known shape and size of the latex balls.
