Electron counting capacitance standard and quantum metrology triangle experiments at PTB
H Scherer, J Schurr, F J Ahlers
This paper summarizes the final results of the electron counting capacitance standard experiment at the Physikalisch-Technische Bundesanstalt (PTB) achieved since the publication o…
Steps towards a capacitance standard based on single-electron counting at PTB
H. Scherer, S. V. Lotkhov, G. -D. Willenberg +1
A capacitance standard based on the definition of capacitance C = Ne/U is realized when a capacitor is charged with a known number N of electrons (e is the elementary charge) and t…
Single-charge devices with ultrasmall Nb/AlOx/Nb trilayer Josephson junctions
R. Dolata, H. Scherer, A. B. Zorin +1
Josephson junction transistors and 50-junction arrays with linear junction dimensions from 200 nm down to 70 nm were fabricated from standard Nb/AlOx/Nb trilayers. The fabrication…
Single electron transistors with high quality superconducting niobium islands
R. Dolata, H. Scherer, A. B. Zorin +1
Deep submicron Al-AlOx-Nb tunnel junctions and single electron transistors with niobium islands were fabricated by electron beam gun shadow evaporation. Using stencil masks consist…
The effect of thermal annealing on the properties of Al-AlOx-Al single electron tunneling transistors
H. Scherer, Th. Weimann, A. B. Zorin +1
The effect of thermal annealing on the properties of Al-AlOx-Al single electron tunneling transistors is reported. After treatment of the devices by annealing processes in forming…
Characterization of All-Chromium Tunnel Junctions and Single Electron Tunneling Devices Fabricated by Direct-Writing Multilayer Technique
H. Scherer, Th. Weimann, P. Hinze +3
We report about the fabrication and analysis of the properties of Cr/CrO_x/Cr tunnel junctions and SET transistors, prepared by different variants of direct-writing multilayer tech…
Superconducting Electrometer Based on the Resistively Shunted Bloch Transistor
S. V. Lotkhov, H. Zangerle, A. B. Zorin +3
We have fabricated the Bloch transistor shunted on-chip by a small-sized Cr resistor with Rs about 1 kOhm. The Bloch transistor normally consists of two small Josephson junctions 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…
