Noise performance & thermalization of single electron transistors using quantum fluids
N. R. Beysengulov, J. R. Lane, J. M. Kitzman +3
We report on low-temperature noise measurements of a single electron transistor (SET) immersed in superfluid He. The device acts as a charge sensitive electrometer able to dete…
Integrating superfluids with superconducting qubit systems
J. R. Lane, D. Tan, N. R. Beysengulov +7
Superfluid helium's low-loss dielectric properties, excellent thermal conductivity, and unique collective excitations make it an attractive candidate to incorporate into supercondu…
Anomalous attenuation of piezoacoustic surface waves by liquid helium thin films
H. Byeon, K. Nasyedkin, J. R. Lane +4
We report on the observation of an anomalously high attenuation of high frequency surface acoustic waves by thin films of liquid He. The piezoelectric acoustic waves propagat…
Unconventional field-effect transistor composed of electrons floating on liquid helium
K. Nasyedkin, H. Byeon, L. Zhang +5
We report on an unconventional field effect transistor composed of electrons floating above the surface of superfluid helium. With this device unique transport regime…
Stick-Slip Motion of the Wigner Solid on Liquid Helium
David G. Rees, Niyaz R. Beysengulov, Juhn-Jong Lin +1
We present time-resolved transport measurements of a Wigner solid (WS) on the surface of liquid Helium confined in a micron-scale channel. At rest, the WS is `dressed' by a cloud o…
