Bulk superinsulation and polar nematic order in nanopatterned NbTiN

A. Yu. Mironov, C. A. Trugenberger, M. C. Diamantini +2

We present an experimental evidence of 3D superinsulation in a nanopatterned slab of NbTiN, given by the Vogel-Fulcher-Tamman (VFT) scaling of the conductance when approaching the…
