Nanofabrication for Fundamental Physics
Researchers are taking advantage of the silicon industry's
development of fabrication tools and techniques to construct
devices with dimensions comparable or smaller than fundamental
physical length scales, such as the Fermi wavevector,
quantum-phase coherence lengths, or the thermal phonon
wavelength in a dielectric suspended beam. Here I will review
some of the basic fabrication techniques by using examples of
some important devices that researchers have made. An
application of particular interest is the possibility to
fabricate a mechanical oscillator which can be prepared in its
quantum mechanical ground state. Once this is realized, one
has a quantum measurement playground; quantum non-demolition,
back-action experiments, squeezed states, etc..
