From taut strings vibrating in musical instruments to
micro-electro-mechanical systems for optoelectronics, vibrations
cover an extensive range of applications. At the nanoscale, the
study of mechanical vibrations poses several challenges and opens
up a virtually infinite playground for nanotechnologies. Exciting
potential benefits of controlled vibrations in the GHz-THz
frequency range include better thermal transport management, novel
quantum acoustic technologies, improved optoelectronic devices, and
the development of novel nanoscale sensors.
