Overactivated transport in the localized phase of the superconductor-insulator transition

Despite extensive work on the superconductor-insulator transition in two-dimensional materials, the nature of the insulator is still debated. The authors report measurements and simulations of NbxSi1–x films, showing that conduction in the insulating state occurs by single charges hopping between su...
