Scanning joule expansion microscopy
Scanning Joule Expansion Microscopy is a form of scanning probe microscopy heavily based on atomic force microscopy that maps the temperature distribution along a surface. Resolutions down to 10 nm have been achieved and 1 nm resolution is theoretically possible. Thermal measurements at the nanometer scale are of both academic and industrial interest, particularly in regards to nanomaterials and modern integrated circuits.
