Critical Velocity in the Presence of Surface Bound States in Superfluid He-B
P. Zheng, W. G. Jiang, C. S. Barquist +2
A microelectromechanical oscillator with a gap of 1.25 m was immersed in superfluid He-B and cooled below 250 K at various pressures. Mechanical resonances of its shear m…
Anomalous Damping of a Micro-electro-mechanical Oscillator in Superfluid He-B
P. Zheng, W. G. Jiang, C. S. Barquist +2
The mechanical resonance properties of a micro-electro-mechanical oscillator with a gap of 1.25 m was studied in superfluid He-B at various pressures. The oscillator was dri…
Temperature Dependence of Viscosity in Normal Fluid He Below 800mK Determined by a Micro-electro-mechanical Oscillator
M. Gonzalez, W. G. Jiang, P. Zheng +3
A micro-electro-mechanical system vibrating in its shear mode was used to study the viscosity of normal liquid He from 20mK to 770mK at 3bar, 21bar, and 29bar. The damping coef…
Comb-drive MEMS Oscillators for Low Temperature Experiments
M. Gonzalez, P. Zheng, E. Garcell +2
We have designed and characterized micro-electro-mechanical systems (MEMS) for applications at low temperatures. The mechanical resonators were fabricated using a surface micromach…
