Origin of the hysteresis in bilayer 2D systems in the quantum Hall regime
L. H. Ho, L. J. Taskinen, A. P. Micolich +3
The hysteresis observed in the magnetoresistance of bilayer 2D systems in the quantum Hall regime is generally attributed to the long time constant for charge transfer between the…
Electrometry using the quantum Hall effect in a bilayer 2D electron system
L. H. Ho, L. J. Taskinen, A. P. Micolich +3
We discuss the development of a sensitive electrometer that utilizes a two-dimensional electron gas (2DEG) in the quantum Hall regime. As a demonstration, we measure the evolution…
Radio-frequency reflectometry on large gated 2-dimensional systems
L. J. Taskinen, R. P. Starrett, T. P. Martin +5
We have embedded an AlGaAs/GaAs based, gated 2D hole system (2DHS) into an impedance transformer circuit, and show that by using radio-frequency reflectometry it is possible t…
Influence of temperature gradients on tunnel junction thermometry below 1 K: cooling and electron-phonon coupling
J. T. Karvonen, L. J. Taskinen, I. J. Maasilta
We have studied thermal gradients in thin Cu and AlMn wires, both experimentally and theoretically. In the experiments, the wires were Joule heated non-uniformly at sub-Kelvin temp…
Electron energy relaxation by phonons in the Kondo condensate
L. J. Taskinen, I. J. Maasilta
We have used normal metal-insulator-superconductor tunnel junctions as thermometers at sub-Kelvin temperatures to study the electron-phonon (e-p) interaction in thin Aluminum films…
Direct measurement of the electron-phonon relaxation rate in thin copper films
L. J. Taskinen, J. M. Kivioja, J. T. Karvonen +1
We have used normal metal-insulator-superconductor (NIS) tunnel junction pairs, known as SINIS structures, for ultrasensitive thermometry at sub-Kelvin temperatures. With the help…
