Picosecond ultrasonics technique

Caption

The figure describes the picosecond ultrasonics technique to probe atomic bonds and vdW forces in In2Se3. In the experiment, blue-coloured pump laser pulses are shined on a flake of 2D material, and red-coloured probe laser pules are used to probe the strength of atomic bonds.
