Nanoscale determination of phase velocity by scanning acoustic force microscopy
We measured the phase velocity of surface acoustic waves (SAW's) with a scanning acoustic force microscope (SAFM) and achieved a maximum lateral resolution of 19.9 nm. The phase measurement of high-frequency waves with a slowly responding SAFM cantilever was perfomed by frequency mixing at its...
