The tunneling current was seen as a result of applied microwave fields
across the junctions, distinguishable from shot noise and resistance effects.
The form of tunneling behavior does not lead to any conductance quantization
effects which could manifest the junction as a Quantum Point Contact (QPC),
hence it is surmised that the phenomenon is purely low intensity RF
field-induced tunneling of electrons across the mesoscale junctions at low
temperatures.</span>
