Edge-mode superconductivity in a two
... Nevertheless, several scenarios have been proposed involving processes with an electron travelling along one edge being Andreevreflected as a hole into the other edge29–33. Such processes require phase coherence in excess of the sample circumference, ∼9 μm, which seems large given previous transport ...
