Hexagonal-structured ε-NbN: ultra-incompressibility, high shear rigidity, and a possible hard superconducting material
Exploring the structural stability and elasticity of hexagonal ε-NbN helps discover correlations among its physical properties for scientific and technological applications. Here, for the first time, we measured the ultra-incompressibility and high shear rigidity of polycrystalline hexagonal ε-NbN using ultrasonic interferometry and in situ X-ray diffraction, complemented with first-principles ...
متن کاملDiscovery of Superconductivity in Hard Hexagonal ε-NbN
Since the discovery of superconductivity in boron-doped diamond with a critical temperature (TC) near 4 K, great interest has been attracted in hard superconductors such as transition-metal nitrides and carbides. Here we report the new discovery of superconductivity in polycrystalline hexagonal ε-NbN synthesized at high pressure and high temperature. Direct magnetization and electrical resistiv...
متن کاملA superconducting NbN detector for neutral nanoparticles.
We present a proof-of-principle study of superconducting single photon detectors (SSPD) for the detection of individual neutral molecules/nanoparticles at low energies. The new detector is applied to characterize a laser desorption source for biomolecules and allows retrieval of the arrival time distribution of a pulsed molecular beam containing the amino acid tryptophan, the polypeptide gramic...
متن کاملSuperconducting properties and Hall Effect of epitaxial NbN thin films
We have measured the magnetotransport properties and Hall effect of a series of epitaxial NbN films grown on (100) oriented single crystalline MgO substrate under different conditions using reactive magnetron sputtering. Hall effect measurements reveal that the carrier density in NbN thin films is sensitive to the growth condition. The carrier density increases by a factor of 3 between the film...

LLE Review, Volume 106 108 Practical quantum cryptography (QC) systems require ultrafast and high-quantum-efficiency (QE) single-photon detectors (SPD’s)1 with precise timing characteristics2 and sufficiently low dark counts. For fiber-optic QC systems, SPD’s working at the standard near-infrared (NIR) telecommunication wavelengths, namely 1.3 nm and/or 1.55 nm, with counting rates well above 1...
