Detection of shorter-than-skin-depth acoustic pulses in a metal film via transient reflectivity

Short acoustic pulses are generated in SrRuO[subscript 3] transducers and detected at the surface of gold films by transient reflectivity. Contrary to expectations, acoustic pulses that are shorter than the optical skin depth of gold are resolved. A comparison of gold detection films that were grown...

Description
Résumé:Short acoustic pulses are generated in SrRuO[subscript 3] transducers and detected at the surface of gold films by transient reflectivity. Contrary to expectations, acoustic pulses that are shorter than the optical skin depth of gold are resolved. A comparison of gold detection films that were grown under different deposition conditions demonstrates that the microstructure of a detection film can impact the shape of the detected signal.
