Features of superconducting transition in nanocomposite consisting of “insulating matrix (porous alkali-borosilicate glass)” – “granular metallic filler (indium)”

Resistivity superconducting transition in single-crystalline Cd0.95Ni0.05Sb system consisting of non-superconducting CdSb and NiSb phases

“…Forming inhomogeneous and disordered structures in solids is usually applied as a fruitful way to tune their properties in a desired manner. Inhomogeneous and disordered conductors and semiconductors often demonstrate unusual and specific features in behavior of their electrical properties, which are related to developing new mechanisms of conductivity and magnetoresistance [1][2][3][4][5][6][7], forming unstable and metastable states [8][9][10], arising strong fluctuation corrections to conductivity, which affect a superconducting transition [11][12][13][14][15], and etc. All the features in the electrical properties are dominantly originated from compositional and phase inhomogeneity, and structural disorder.…”
