Impurity superconductor
WitrynaMotivated by Sr2RuO4, we consider a chiral superconductor where the gap is strongly suppressed along certain momentum directions. We evaluate the thermal Hall conductivity in the gapless regime, i.e. WitrynaThe meaning of SUPERCONDUCTIVITY is a complete disappearance of electrical resistance in a substance especially at very low temperatures.

Witryna15 paź 2009 · 1.. IntroductionOne of the most interest issues in the research of two-gap superconductivity is the impurity effect. In a typical two-gap superconductor MgB 2, extensive studies of impurity effect have been carried out, such as the substitution of C for B and of Al for Mg [1], [2].However, these substitutions can change the electronic … As the electron doping of RbxC60 deviates slightly from half-filling, subsurface tetragonal Rb vacancies emerge as dark windmills as x < 3, whereas excess K adatoms appear and occupy the octahedral sites as x > 3. Analogous to KxC60 (Supplementary Figure 6a, b)37, they do not alter profoundly the orientation … Zobacz więcej Figure 1a depicts a representative STM topography of nine monolayer (ML) Rb3C60 thin films epitaxially grown on graphitized SiC(0001) substrates.
