“…Niobium-titanium wire has been used as leads for composite bolometers operating below 100 mK 3 and was easily adaptable to higher temperatures, with a critical temperature of 9.26 K. Because the wires superconduct, the electrical resistance is negligible, and the thermal conductivity is dominated by the lattice. Extrapolating from measurements at higher temperatures, 4 we estimate that the thermal conductivity should be 1.5 ϫ 10…”

We report the design and performance of 300-mK composite bolometers that use micromesh absorbers and support structures patterned from thin films of low-stress silicon nitride. The small geometrical filling factor of the micromesh absorber provides 20ϫ reduction in heat capacity and cosmic ray cross section relative to a solid absorber with no loss in IR-absorption efficiency. The support structure is mechanically robust and has a thermal conductance, G Ͻ 2 ϫ 10 Ϫ11 W͞K, which is four times smaller than previously achieved at 300 mK. The temperature rise of the bolometer is measured with a neutron transmutation doped germanium thermistor attached to the absorbing mesh. The dispersion in electrical and thermal parameters of a sample of 12 bolometers optimized for the Sunyaev-Zel'dovich Infrared Experiment is Ϯ7% in R͑T͒, Ϯ5% in optical efficiency, and Ϯ4% in G.

“…Some of those works [12,[19][20][21][22][23][24] describe alloys being formed from cathode substrate and Nb deposited. However, there are only a few works [11,22,23,25,26] describing Al and Nb co-deposition that results in Nb-Al alloy formation and those are on W, Cu and Nb cathodes, but not on vitreous carbon.…”

Niobium and aluminium were electrodeposited at 200 °C under argon atmosphere onto vitreous carbon from inorganic chloroaluminate melts (AlCl 3 +NaCl) with added niobium. Niobium was introduced into the electrolyte by anodic dissolution of metallic niobium or by chemical dissolution of Nb 2 O 5 in a melt of equimolar AlCl 3 +NaCl mixture. The processes of deposition/dissolution onto/from vitreous carbon were investigated by cyclic voltammetry and chronoamperometry. Characterization of the obtained deposits was done by Scanning Electron Microscopy (SEM) and Energy Dispersive Spectroscopy (EDS). The only observed reduction processes on the working electrode in the potential window from 1.000 V to -1.000 V vs. Al, were individual niobium deposition and codeposition of niobium and aluminium with Al-Nb alloys formation.Electrodeposition of niobium from the chloroaluminate melt with added niobium (V) oxide seems to start at around -0.100 V vs. Al and at about -0.200 V vs. Al aluminium starts codepositing. During the codeposition Nb-Al alloys were formed. Niobium deposition starting potential from the electrolyte with niobium added by anodic dissolution starts at 0.100 V vs. Al, and aluminium codeposition starting potential was at around -0.025 V vs. Al, followed by Nb/Al alloy formation.
