Abstract

We present a new technique, Optical Heterodyne Force Microscopy, that allows local probing of photothermally-induced ultrasonic vibrations of a sample surface. We demonstrate with images of a sample of highly-oriented pyrolytic graphite obtained at megahertz optical modulation frequencies that lateral resolution of surface and subsurface variations in thermal properties can be achieved on nanometer scales.
