Abstract

This paper describes the preparation and properties of various types of SIN devices: Pb/Bi/In-oxide-Ag junctions, evaporated through metal masks and three slightly different types of Nb/Al-based junctions, applying “trilayer-technique”, similar as for Nb-Aloxide-Nb SIS junctions. These three types are: Al(thick)-Alox/Al-Nbl, Nb-Alox-All(thick), Nb-Alox-Al(thick)-Nbl. We show the anodization profiles of these trilayers and compare experimental I–V characteristics with theory. Photon steps were observed at 370 GHz.
