| Research Abstract |
Accurate evaluation of elastic properties of nanoscale thin films is an important issue in nanoscience and nanotechnology. We have developed the picosecond ultrasound spectroscopy method for the measurement of the elastic constant of nanoscale thin films and present its application to nondestructive evaluation method for reliability of nanomaterials.
