Large Area Composite AFM Image Created by Parallel Scanning of Cantilever Array

A 550 µm x 90 µm composite AFM image consisting of 26.4 million pixels, acquired simultaneously with an array of five heated cantilevers. The array scanned the sample in contact-mode AFM at 4000 µm/sec and the image was acquired in 125 s. Each cantilever scanned three adjacent rectangular areas and the resulting 15 scans were stitched together to make the complete image. Imaged on a MFP-3D AFM.
