The drift distorts the atomic force microscopy (AFM) images as the time taken to acquire a complete AFM image is relatively long (a few minutes). As the AFM image is used as a reference for most manipulation mechanisms, the image distorted by drift will cause problems for AFM-based manipulation because the displayed positions of the objects under nanomanipulation do not match their actual locations...
Because of the presence of thermal drift, AFM (atomic force microscopy) images are always contaminated. Such contamination is one of the major hampers to achieve accurate and efficient AFM based nanomanipulation. Based on contaminated images, the manipulation operations often fail. In this paper, we apply a local scan method to identify and compensate the thermal drift contamination in the AFM image...
Thermal drift in atomic force microscopy (AFM) is one of the major hurdles to achieve accurate and efficient AFM based nanomanipulation. AFM images are all contaminated by the thermal drift which often leads to failed manipulation operations. In this paper, a local scan strategy is applied to identify the thermal drift contamination in the AFM image and then the draft contamination is compensated...
