【 摘 要 】

High-frequency vibrations related with copper nanowires on a silicon substrate are studied using picosecond ultrasound spectroscopy. The reflectivity change in the probe light pulse is monitored after irradiation of the specimen with the ultrafast light pulse, showing high (similar to 75 GHz) and low (
