Terahertz transmission spectroscopy by Josephson oscillator and cold-electron bolometer [PDF]

SPIE Proceedings, 2004
For sensitive wideband spectroscopy at TeraHertz frequencies one needs a wide-range electrically tunable THz source and a sensitive detector. In this paper a superconducting normal metal cold electron bolometer (CEB) was used as a broadband sensor. Bolometers were integrated with broadband log-periodic antenna designed for 0.2-2 THz frequency range ...

Multichroic bandpass seashell antenna with cold-electron bolometers for CMB measurements [PDF]

SPIE Proceedings, 2016
A novel type of the multichroic "seashell" resonant antenna is developed for CMB measurements. The polarized slot antennas are arranged in the compact form of a seashell with individual slots for each frequency and each polarization. Such an arrangement gives unique opportunity for independent adjusting individual parameters of slots with microstrip ...

Cold-electron bolometers for future mm and sub-mm sky surveys [PDF]

SPIE Proceedings, 2014
Future sky surveys in the mm/sub-mm range, like the forthcoming balloon-borne missions LSPE, OLIMPO, SPIDER etc., will need detectors insensitive to cosmic rays (CRs) and with a NEP of the order of $10^{-17} ÷10^{-18}\,$W/sqrt(Hz). The Cold-Electron Bolometers (CEBs) technology is promising, having the required properties, since the absorber volume is ...

Influence of Metal Oxide Interface Layers on the Thermochromic Properties of VO2 Thin Films Deposited by Magnetron Sputtering

Advanced Materials Interfaces, Volume 13, Issue 4, 17 February 2026.
This study investigates the thermochromic properties of VO2 deposited on aluminum doped zinc oxide precoated fused silica with Al2O3, TiO2, and WO3 as interface layers. The results indicate that the metal‐to‐insulator transition is highly influenced by the grains formed at the interface.

Superconducting Nanowire Detection of Neutral Atoms and Molecules via Their Internal and Kinetic Energy in the eV Range

Advanced Physics Research, Volume 4, Issue 2, February 2025.
Superconducting nanowires are a powerful tool for detecting metastable atoms and low‐energy neutral molecules. These nanowires achieve remarkable gains in detection efficiency, spatial resolution, and signal‐to‐noise ratio, responding sensitively to atomic internal energies between 10 and 20 eV and molecular kinetic energies from 3 to 6 eV.

Decoupled High‐Mobility Graphene on Cu(111)/Sapphire via Chemical Vapor Deposition

Advanced Materials, Volume 36, Issue 44, November 1, 2024.
The growth via chemical vapor deposition of decoupled graphene on crystalline Cu(111) films deposited on sapphire is introduced. The resulting graphene is lying atop a thin Cu2O layer and is charge neutral, low strained, and easy to transfer. Electrical transport measurements reveal excellent room temperature carrier mobilities, exceeding 105 cm2 V−1 s−
