This data set consists of ten atomic force microscopy images in MI format as well as corresponding previews in PNG format. The microscopy images are of various materials and have been scanned with AFM equipment from Keysight Technologies. Details on the individual images: image_7.mi - calibration grid with 5 µm pitch size image_8.mi - Celgard (a polymer membrane used in batteries) image_9.mi - Titanium-Tungsten film image_10.mi - AFM image image_11.mi - self-assembled monolayer of lipids on gold image_12.mi - capacity calibration sample for Scanning Microwave Microscopy imaging image_13.mi - capacity calibration sample for Scanning Microwave Microscopy imaging image_14.mi - PS-LDPE-12M (a polymer blend of Polystyrene and Polyolefin Elastomere) image_15.mi - AFM Calibration grid image_16.mi - AFM Calibration grid The images can be opened using, e.g. Gwyddion: http://gwyddion.net/ The Python package Magni can be used to load the images into Python (using the magni.afm.io module): https://github.com/SIP-AAU/Magni The images are provided as-is without warranty of any kind.
