Ionic conductivity enhancement of polymer electrolytes with ceramic nanowire fillers.
Solid-state electrolytes provide substantial improvements to safety and electrochemical stability in lithium-ion batteries when compared with conventional liquid electrolytes, which makes them a promising alternative technology for next-generation high-energy batteries. Currently, the low mobility of lithium ions in solid electrolytes limits their practical application. The ongoing research ove...
متن کاملAging effect in ceramic superconductors.
A three-dimensional lattice of the Josephson junctions with a finite self-conductance is employed to model ceramic superconductors. By using Monte Carlo simulations it is shown that the aging disappears in the strong screening limit. In the weak screening regime, aging is present even at low temperatures. For intermediate values of the self-inductance, aging occurs in an intermediate temperatur...
متن کاملOptical conductivity of d-wave superconductors
– We study theoretically the optical conductivity of d-wave superconductors like in high temperature cuprates in the presence of impurities. We limit ourselves at T = 0K and focus on the frequency dependence of both σ1(ω) and ωσ2(ω) for ω . 2∆. When the impurity scattering is in the unitary limit, we find a peak in σ1(ω) with ω/∆ ≃ 0.1 ∼ 0.5, which may account for the peak seen by Basov et al. ...
متن کاملOptical conductivity of iron-based superconductors.
The new family of unconventional iron-based superconductors discovered in 2006 immediately relieved their copper-based high-temperature predecessors as the most actively studied superconducting compounds in the world. The experimental and theoretical effort made in order to unravel the mechanism of superconductivity in these materials has been overwhelming. Although our understanding of their m...
متن کاملHolographic conductivity of zero temperature superconductors
Using the recently found by G. Horowitz and M. Roberts (arXiv:0908.3677) numerical model of the ground state of holographic superconductors (at zero temperature), we calculate the conductivity for such models. The universal relation connecting conductivity with the reflection coefficient was used for finding the conductivity by the WKB approach. The dependence of the conductivity on the frequen...
