Exceptionally accurate large graphene quantum Hall arrays for the new SI
Hans He, Karin Cedergren, Naveen Shetty +4
The quantum Hall effect (QHE) is a cornerstone in the new International System of Units (SI), wherein the base units are derived from seven fundamental constants such as Planck's c…
Experimental demonstration of the time reversal Aharonov-Casher effect
Tobias Bergsten, Toshiyuki Kobayashi, Yoshiaki Sekine +1
We demonstrate the time reversal Aharonov-Casher (AC) effect in small arrays of mesoscopic semiconductor rings. By using an electrostatic gate we can control the spin precession ra…
Coulomb blockade thermometry using a two-dimensional array of tunnel junctions
Tobias Bergsten, Tord Claeson, Per Delsing
We have measured current-voltage characteristics of two-dimensional arrays of small tunnel junctions at temperatures from 1.5 K to 4.2 K. This corresponds to thermal energies large…
A fast, primary Coulomb blockade thermometer
Tobias Bergsten, Tord Claeson, Per Delsing
We have measured the third derivative of the current-voltage characteristics, d^3I/dV^3, in a two-dimensional array of small tunnel junctions using a lock-in amplifier. We show tha…
Two-dimensional arrays of low capacitance tunnel junctions: general properties, phase transitions and Hall effect
P. Delsing, C. D. Chen, D. B. Haviland +2
We describe transport properties of two-dimensional arrays of low capacitance tunnel junctions, such as the current voltage characteristic and its dependence on external magnetic f…
