Abstract:
We introduce an analytical expression, modeling the photothermal expansion process and validating it with finite element simulations and AFM-IR experiments. These results enable experimentalists to achieve high signal intensity and high spatial resolution in AFM-IR experiments through selection of excitation laser parameters and accounting for material properties and sample geometries in both 2D and 3D chemical imaging.
