Nanoscale Real-Time Detection of Quantum Vortices at Millikelvin Temperatures
A. Guthrie, S. Kafanov, M. T. Noble +6
Since we still lack a theory of classical turbulence, attention has focused on the conceptually simpler turbulence in quantum fluids. Can such systems of identical singly-quantized…
High quality factor mechanical resonance in a silicon nanowire
D. E. Presnov, S. Kafanov, A. A. Dorofeev +4
Resonance properties of nanomechanical resonators based on doubly clamped silicon nanowires, fabricated from silicon-on-insulator and coated with a thin layer of aluminum, were exp…
Cooper Pair Transport in a Resistor-Biased Josephson Junction Array
Sergey V. Lotkhov, Vladimir A. Krupenin, Alexander B. Zorin
The dc transport properties of long arrays of small Al Josephson junctions, biased through on-chip Cr resistors, are studied. The IV-characteristics show a large Coulomb threshold…
Metallic single-electron transistor without traditional tunnel barriers
V. A. Krupenin, A. B. Zorin, D. E. Presnov +2
We report on a new type of single-electron transistor (SET) comprising two highly resistive Cr thin-film strips (~ 1um long) connecting a 1 um-long Al island to two Al outer electr…
Aluminum Single Electron Transistors with Islands Isolated from a Substrate
V. A. Krupenin, D. E. Presnov, A. B. Zorin +1
The low-frequency noise figures of single-electron transistors (electrometers) of traditional planar and new stacked geometry were compared. We observed a correlation between the c…
Noise in Al single electron transistors of stacked design
V. A. Krupenin, D. E. Presnov, M. N. Savvateev +3
We have fabricated and examined several Al single electron transistors whose small islands were positioned on top of a counter electrode and hence did not come into contact with a…
Multilayer technique developed for fabricating Nb-based single-electron devices
Alexey B. Pavolotsky, Thomas Weimann, Hansjoerg Scherer +3
A reliable process has been developed for the fabrication of all-Nb single-electron circuits, based on spin-on glass planarization. The process steps are the in situ growth of Nb/A…
