Imaging superconducting weak spots through vortex-assisted THz near-field photovoltage

Sergio J. Salvía-Fernández, Ekaterina Khestanova, Zoe Velluire-Pellat +9

Nanoscale inhomogeneities are a defining feature of many superconducting materials, yet their local electromagnetic response has remained difficult to access experimentally. This i…

Revealing intrinsic superconductivity of the Nb/BiSbTeSe interface

Andrei Kudriashov, Ian Babich, Razmik A. Hovhannisyan +7

Typically, topological superconductivity is reachable via proximity effect by a direct deposition of superconductor (S) on top of a topological insulator (TI) surface. Here we obse…

Enhanced superconductivity in few-layer TaS due to healing by oxygenation

J. Bekaert, E. Khestanova, D. G. Hopkinson +15

When approaching the atomically thin limit, defects and disorder play an increasingly important role in the properties of two-dimensional materials. Superconductivity is generally…

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 potassium-doped metallic polymorphs of MoS2

Renyan Zhang, I-Ling Tsai, James Chapman +3

Superconducting layered transition metal dichalcogenides (TMDs) stand out among other superconductors due to the tunable nature of the superconducting transition, coexistence with…
