81. Capacitive readout technique for studies of dissipation in GaN nanowire mechanical resonators
Kristine A Bertness, Joshua R. Montague, Norman A Sanford, Victor Bright, C. T. Rogers
A variable-temperature, homodyne reflectometry measurement technique for detecting nanoscale mechanical motion has recently been developed. We have extended this technique to make the first all-electrical measurements of an ensemble of as-grown, c-a ...
82. High-Precision Pressure Shifting Measurement Technique Using Frequency-Stabilized Cavity Ring-Down Spectroscopy
D J Robichaud, Joseph Terence Hodges, D Lisak, Charles E Miller, Mitchio Okumura
We describe a high-precision method for measuring pressure shifting of absorption lines. The technique involves the acquisition of high-resolution spectra using a cavity ring-down spectrometer whose length is continuously locked to a frequency-stabil ...
