Singlet and triplet Cooper pair splitting in superconducting-semiconducting hybrid nanowires

Kavli Affiliate: Michael Wimmer | First 5 Authors: Guanzhong Wang, Tom Dvir, Grzegorz P. Mazur, Chun-Xiao Liu, Nick van Loo | Summary: In most naturally occurring superconductors, electrons with opposite spins are paired up to form Cooper pairs. This includes both conventional $s$-wave superconductors such as aluminum as well as high-$T_c$, $d$-wave superconductors. Materials with […]
