Our paper entitled “Spectroscopy of the superconducting proximity effect in nanowires using integrated quantum dots” appeared in the new open access Nature Journal Communications Physics.

We investigated the very first superconductor-nanowire hybrid devices with tunnel barriers grown during the nanowire growth. Two tunnel barriers (blue) form a quantum dot (red), often referred to as an artificial atom, which constitutes one of the most fundamental building blocks in nano and quantum electronics. These quantum dots are electrically and spatially very well defined, which allows us to perform systematic tunnel spectroscopy measurements of the evolution of the superconducting proximity region of a nanowire segment close to the superconducting contact.
