Efficiency of electron cooling in cold-electron bolometers with traps [PDF]

Beilstein Journal of Nanotechnology, 2022
Electron on-chip cooling from the base temperature of 300 mK is very important for highly sensitive detectors operating in space due to problems of dilution fridges at low gravity.

Responsivity and Noise Equivalent Power of a Single Cold-Electron Bolometer [PDF]

Applied Sciences, 2021
We have developed a single-pixel capacitively coupled Cold-Electron Bolometer (CEB) and characterized it in the current-biased regime. The most attractive feature of the CEB is effective electron self-cooling of the absorber, which leads to a lower ...

Electromagnetic study of a split-ring resonator metamaterial with cold-electron bolometers [PDF]

Beilstein Journal of Nanotechnology
We present an electromagnetic study of a metamaterial receiver based on split-ring resonators with integrated cold-electron bolometers. We suggest a modified antenna design that allows one to significantly increase the absorbed power and the bandwidth ...

Record electron self-cooling in cold-electron bolometers with a hybrid superconductor-ferromagnetic nanoabsorber and traps [PDF]

Scientific Reports, 2020
The Cosmic Microwave Background (CMB) radiation is the only observable that allows studying the earliest stage of the Universe. Radioastronomy instruments for CMB investigation require low working temperatures around 100 mK to get the necessary ...

A Distributed Terahertz Metasurface with Cold-Electron Bolometers for Cosmology Missions [PDF]

Applied Sciences, 2021
We developed and tested a 2D periodic array of cold-electron bolometers arranged into a wideband frequency selective metasurface that absorbs more than 70% of the incident power in the frequency range 100–800 GHz.

Finline-integrated cold electron bolometer [PDF]

Proceedings of SPIE, 2010
The Cold-Electron Bolometer (CEB) is a sensitive millimetre-wave detector which is easy to integrate with superconducting planar circuits. CEB detectors have other important features such as high saturation power and very fast response. We have fabricated and tested CEB detectors integrated across the slot of a unilateral finline on a silicon substrate.

A Bunch of YBCO Josephson Generators for the Analysis of Resonant Cold-Electron Bolometers

Applied Sciences, 2022
The resonant properties of Cold-Electron Bolometers (CEBs) located at a 0.3 K cryostat plate are measured using a 50 μm long high-temperature YBa2Cu3O7−δ (YBCO) Josephson junction oscillator, placed on a 2.7 K plate of the same cryostat.

Quantum Efficiency of Cold Electron Bolometer Optical Response [PDF]

IEEE Transactions on Terahertz Science and Technology, 2014
In this paper, we present the measurements of optical response dependence on power load of a Cold Electron Bolometer integrated in a twin slot antenna. These measurements are also compared to the models of the bolometer limit and the photon counter limit.
