Kinetic Inductance Characterization of Thin 2H-NbSe₂ Superconductor Using Circuit Quantum Electrodynamics
… established a reliable technique to contact thin NbSe₂, entirely encapsulated with hexagonal Boron Nitride (hBN), with a coplanar Al resonator. Then we fabricated hybrid Al-NbSe₂ resonators and measured the kinetic inductance of thin NbSe₂ at low-temperature and low-photon number limits. In this …

Superconductivity and low temperature properties of niobium diselenide single crystals grown by direct vapor transport
… for the growth of high purity single crystals of 2H-NbSe₂ by a direct vapor transport (DVT) method was developed. Single crystal growth rate and the degree of crystal perfection were studied as deviations from stoichiometry were made over the compositional range of Nb<sub>0.95</sub>Se₂ to …

Raman Scattering From the Superconductor Niobium-Diselenide
At 33 K 2H-NbSe(,2) distorts into an incommensurate charge density wave (CDW) state. The Raman spectrum shows amplitude modes of A and E symmetry near 40 cm('-1) induced by the CDW. At 7 K this material becomes superconducting, and at 2 K we observe additional Raman peaks near 20 cm('-1), one each …

Zero Field Nmr Study on a Spin Glass: Iron-Doped 2hydrogen-Niobium Diselenide
… used spin echoes to study the ('93)Nb NQR in 2H-NbSe(,2)Fe(,x). We measured (intensity) x (temperature), and T(,1P) (spin-lattice relaxation parameter) and T(,2) (spin-spin relaxation time) as a function of temperature. Our data reveal dramatic difference between non-spin glass samples (x = 0, …

Correlation lengths, disorder, and dynamics of vortex matter as heard through the noise
… voltage noise in the type II superconductor 2H-NbSe₂ concentrating on the dynamics and possible phase transitions of vortex matter associated with the peak-effect. I emphasize five conclusions: (1) Traditional models of vortex dynamics relying on purely dynamical correlations, rigid bundles, …
