Charge transport in layered structures formed by a metal injector, a nanoscale insulator, a normal-metal interlayer, and an investigated superconductor is discussed theoretically. As shown, the measurements of the differential conductance of such structures could provide unambiguous evidence for the presence of two energy gaps in the superconductor.

Key words: multilayered heterostructures, superconducting electrode, two-gap model, differential conductance.
