Mid-infrared spectroscopy beyond the diffraction limit via direct measurement of the photothermal effect. Issue 42 (12th October 2015) - Katzenmeyer, A. M.
Abstract : Scanning thermal infrared microscopy (STIRM) is a novel method that provides the chemical composition and thermal conductivity information with nanoscale resolution. Abstract : An atomic force microscope equipped with temperature sensitive probes was used to measure locally the photothermal effect induced by IR light absorption. This novel instrument opens a pathway to correlated topographical, chemical composition, and thermal mapping with nanoscale resolution. Proof of principle demonstration is provided on polymers and plasmonic samples.
