“…Porous silicon (PS) is an even more promising self-assembled template for superconductors because silicon is very usefully used as a substrate for the deposition of refractory superconductors, such as Nb and NbN that currently are most widely utilized in superconducting electronics. PS is constituted by a network of pores distributed in nanocrystalline silicon matrix (Bisi et al 2000), and it is a material that offers a considerable technological interest in different fields (Cunin 2014). The possibility of changing the porosity of PS up to high values leads to another unique opportunity, namely, to the use of PS templates to create one-dimensional (1D) superconductors and/or networks of 1D superconducting channels or nanowires (NW).…”

The use of porous silicon (PS) templates in the field of superconducting nanoelectronics is reviewed. We focus on the influence of the morphology of the pores (porosity, average pore diameter) on the superconducting properties of ultrathin films deposited on these templates. We describe and discuss some basic and advanced properties of the obtained nanostructured superconductors. In particular, we show that, due to the extremely reduced dimensions of PS templates, the formation of commensurate vortex structures can be realized at low temperatures and at matching fields as high as μ 0 H 1 % 1 T. We also show that with this fabrication procedure, we can obtain networks of one-dimensional superconducting nanowires, which exhibit features typical of quantum phase slip (QPS) phenomena. This creates preconditions for the development and implementation of new highly sensitive radiation detectors, magnetometers, QPS qubits, QPS transistors, and quantum current standards.
