Nanomechanical resonant devices have been under study for about the past 10 years, due to their ability to achieve very high operating frequencies (approaching 10 GHz), their extremely small mass (approaching tens of femtograms), and their very high sensitivity to changes in parameters, local forces, and their potential for achieving quantum limited motion. There are efforts underway to develop these devices as mass sensors, molecular detectors (both in fluid and in vacuum), electrometers, and there are attempts to integrate them with displacement sensors in order to achieve ultrasmall force detection and possibly measurements at the limit of single phonons, the quanta of mechanical vibrations. In this talk, I will attempt to outline the basic properties of nanomechanical resonators, point out some interesting applications, and outline how their quantum behavior can perhaps be measured.

Prof. Andrew Cleland is a professor at University of California, Santa Barbara. He has been working on various aspects of nanofabrication technology for years. His research interests include the physics of nanoscale electronic and mechanical devices, with present focusses on cellular and molecular biosensing using radiofrequency techniques, quantum computation with Josephson phase qubits, and ultrafast bolometry and calorimetry using nanoscale superconductor-insulator-normal metal tunnel junctions.
