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. Evidently, not all C60 molecules have the same … Zobacz więcej Having established the merohedral disorder-independent superconductivity in fullerides, we then explore its dependence on thickness and electron filling. Elaborated in … Zobacz więcej To fully understand the impurity impact on fulleride superconductivity, we intentionally deposited Fe atoms on Rb3C60 surface at low temperature … Zobacz więcej Witryna11 kwi 2024 · Topological superconductors are foreseen as good candidates for the search of Majorana zero modes, where they appear as edge states and can be used for quantum computation. In this context, it becomes necessary to study the robustness and behavior of electron states in topological superconductors when a magnetic or non …

Witryna2 mar 2024 · We present a study of the superconducting properties of the candidate topological superconductor Ti3Sb. Electrical transport measurements show zero resistance with a T c,onset of ≈5.9 K with a transition width ΔT c≈ 0.6 K. The superconducting phase boundaries as derived from magnetotransport and magnetic … Witryna24 mar 2024 · Nonmagnetic disorder destroys this type of triplet correlations. As a result, the critical temperature of the S/AF bilayer grows with impurity strength. The second mechanism, on the contrary, suggests that nonmagnetic impurity scattering suppresses superconductivity in S/AF hybrids. highlandhills.org
