摘要：

An earlier developed method for fabrication of an Nb tunnel junction with an AlOx interlayer has been used for preparing several types of superconducting double-barrier structures: Nb/Al/Nb, Nb/Nb'/Nb and Nb/Nb'/Al (/ indicates an AlOx tunnel barrier), the Al and Nb' interlayer thickness is 5-20 nm. High resolution TEM analysis shows that the interface between the metal and tunnelling layer is atom sharp and that the barrier film is amorphous. The I-V curves of the structures have been measured.
