By aligning a UV laser perpendicular to an atomic force microscope cantilever it becomes possible to concurrently measure all different sorts of functional properties in contact mode as they vary with temperature. This approach offers valuable insights into the localized characteristics of phase transitions. Additionally, this technique can be utilized to measure the local thermal conductivity.
Of particular interest, it is the combination of thermally modulated cantilevers with nanomechanical measurements, using for example contact ressonance frequency AFM or pieroelectric measurements utilizing band excitation piezoresponse spectroscopy.
