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

Superconducting Contacts to MoS2

Mehdi Ramezani’s paper entitled Superconducting Contacts to a Monolayer Semiconductor just appeared today (24th of June 2021) in Nano Letters. See:  link-to-paper Schottky barriers in semiconductors usually prohibit achieving transparent enough contacts required to induce superconductivity in the semiconductor by the
