Thermoelectric bolometers based on ultra-thin heavily doped single-crystal silicon membranes
Andrey V. Timofeev, Aapo Varpula, Andrey Shchepetov +5
We present ultra-thin silicon membrane thermocouple bolometers suitable for fast and sensitive detection of low levels of thermal power and infrared radiation at room temperature.…
Brownian refrigeration by hybrid tunnel junctions
J. T. Peltonen, M. Helle, A. V. Timofeev +3
Voltage fluctuations generated in a hot resistor can cause extraction of heat from a colder normal metal electrode of a hybrid tunnel junction between a normal metal and a supercon…
Electronic Refrigeration at the Quantum Limit
Andrey V. Timofeev, Meri Helle, Matthias Meschke +2
We demonstrate quantum limited electronic refrigeration of a metallic island in a low temperature micro-circuit. We show that matching the impedance of the circuit enables refriger…
Wide-band detection of the third moment of shot noise by a hysteretic Josephson junction
A. V. Timofeev, M. Meschke, J. T. Peltonen +2
We use a hysteretic Josephson junction as an on-chip detector of the third moment of shot noise of a tunnel junction. The detectable bandwidth is determined by the plasma frequency…
Detecting Current Noise with a Josephson Junction in the Macroscopic Quantum Tunneling Regime
J. T. Peltonen, A. V. Timofeev, M. Meschke +1
We discuss the use of a hysteretic Josephson junction to detect current fluctuations with frequencies below the plasma frequency of the junction. These adiabatic fluctuations are p…
