An Atomic Force Microscope (Park NX10) has been used to measure surface height (Z) and thermal conductivity variations of a sample OREX-800055-9. Images are created using Conductivity Contrast Mode. Measured forward current is proportional to sample thermal conductivity. These images are our first look at the sample and therefor may not have been collected under optimal conditions. Latter images may have different collection parameters.

Software routines to read the raw numbers and embeded meta data from the tiff files. Code is provided to read and display the tiff imagery in python and Matlab. The Matlab code was kindly provided by Park System the maker of the AFM used and shared with permission. If you use the Matlab code please retain the orginal copyright notice. The matlab code was essentially ported to python and has been used to produce the metadata files included here. File 1 ParkSystemsTiffDisplay.m  will display a tiff file read by ParkSystemTiffReader in Matlab.
