Nanomechanical Systems Probed by Electron Tunneling
(University of California at Santa Barbara)
Abstract: My group has been integrating active electronic devices
with nanomechanical systems, in order to probe both the mechanical and
thermodynamical behavior of the integrated system. I will discuss experiments in
which we use superconductor-normal metal tunnel junctions to develop an
ultrasensitive bolometer and calorimeter, with which we have been able to
confirm the observation of the quantum of thermal conductance, the integration
of single-electron transistors with mechanical resonators, displacement sensing
using an integrated quantum point contact, and the development of a double
quantum dot integrated with an L-band mechanical resonator. I will briefly
discuss the potential application of these types of integrated probes for
quantum-limited measurements.
