Unusual suppression of the superconducting energy gap and critical temperature in atomically thin NbSe2
Ekaterina Khestanova, John Birkbeck, Mengjian Zhu +12
It is well known that superconductivity in thin films is generally suppressed with decreasing thickness. This suppression is normally governed by either disorder-induced localizati…
Superconductivity in Ca-doped graphene
J. Chapman, Y. Su, C. A. Howard +6
Graphene, a zero-gap semimetal, can be transformed into a metallic, semiconducting or insulating state by either physical or chemical modification. Superconductivity is conspicuous…
Long-range nonlocal flow of vortices in narrow superconducting channels
I. V. Grigorieva, A. K. Geim, S. V. Dubonos +5
We report a new nonlocal effect in vortex matter, where an electric current confined to a small region of a long and sufficiently narrow superconducting wire causes vortex flow at…
