WebAtomic-force microscopy (AFM) is a surface scanning technique that has sub-nanometer scale resolution. AFM describes a group of techniques used for non-destructive surface studies at the nanoscale. They have a resolution on the order of 103 times better than optical microscopy’s resolution limit. WebTopography imaging at the nanoscale is one of the main scopes of AFM. Analysis of chemical composition and structure of various blends, block-copolymers, fibres, crystallites and single molecules is primarily based on visualization of topography data.

WebAFM Topography image of poly (styrene-butadiene-styrene) (SBS) and polystyrene (PS) AFM Phase image of poly (styrene-butadiene-styrene) (SBS) and polystyrene (PS) An additional challenge of phase imaging is a propensity towards imaging artifacts such as reversal of contrast or loss of contrast. WebGenerally, in AFM, the topography of a sample surface is measured via the “bi-cell” signal of the quad-cell PSPD, commonly called vertical signal (A-B). This signal originates from the difference between the upper cells (a+c) and the lower cells (b+d) of the quad-cell PSPD, as shown in figure 1. Topography information = (a+c) – (b+d)
