2. Description of the AFM-IR technique
2.1 Local absorption measurement
The AFM-IR technique (figure 1 ) involves illuminating a sample with a wavelength-tunable IR laser source while probing it with the tip of an atomic force microscope (patent US 2008/0283,755). If this laser source is tuned to a wavelength corresponding to one of the sample's absorption bands, a photothermal effect is generated. The AFM tip is then used as a detector of this absorption.
