Disorder effects in planar semiconductor-superconductor structures: Majorana wires versus Josephson junctions
Purna P. Paudel, Nathan O. Smith, Tudor D. Stanescu
Disorder effects in hybrid semiconductor-superconductor (SM-SC) nanowires, widely recognized as the main obstacle to realizing stable Majorana zero modes (MZMs) in these structures…
