Ferromagnetic resonant tunneling diodes as spin polarimeters and polarizers
Francesco Giazotto, Fabio Taddei, Rosario Fazio +1
A method for measuring the degree of spin polarization of magnetic materials based on spin-dependent resonant tunneling is proposed. The device we consider is a ballistic double-ba…

Josephson current in ballistic Nb/InAs/Nb highly transmissive junctions
Francesco Giazotto, Kasper Grove-Rasmussen, Rosario Fazio +3
Highly transmissive ballistic junctions are demonstrated between Nb and the two-dimensional electron gas formed at an InAs/AlSb heterojunction. A reproducible fabrication protocol…
