4e Supercurrent

4e Supercurrent

We are thrilled to share our new paper entitled “Charge-4e supercurrent in a two-dimensional InAs-Al superconductor-semiconductor heterostructure” by Carlo Ciaccia.  Supercurrent is carried by Cooper pairs having charge 2e. Accordingly, the second Josephson equation, which relates an AC supercurrent with
