The use of picosecond acoustic phonon pulses for the nanoscale acoustic imaging was analyzed. Nanoscale acoustic imaging was use to characterize the nanomaterials and nanoelectronic devices, and also for acoustic cryomicroscopy of biological samples. The ultrafast optical pulses were used to generate high-frequency acoustic pulses by impulsive thermoelastic excitation of a patterned 15-nm-thick metal films on a crystalline substrate. The 1-micron-period Al structures on Si, which was lithographically defined, was used to characterize the image resolution.
