World's Smallest Superconductor Discovered 72

arcticstoat writes "One of the barriers to the development of nanoscale electronics has potentially been eliminated, as scientists have discovered the world's smallest superconductor. Made up of four pairs of molecules, and measuring just 0.87nm, the superconductor could potentially be used as a nanoscale interconnect in electronic devices, but without the heat and power dissipation problems associated with standard metal conductors."

    First, this is not a type II. It's not a BCS superconductor at all.
    In fact, given that they do not show Meissner effect, one wonders how they conclude it is a superconductor. Heck, the paper does not even show resistance - just a density of states which is depressed at Fermi level. That could be due to anything (like a CDW). This paper seems like it is full of shit until proven otherwise. I would not pass it if I were the reviewer.

    The superconductor is a type of organic salt placed on a silver substrate

    I wonder how they test for superconductivity when placing this tiny conductor on a substrate of massive silver, known as the best conductor there is, excluding superconductors.

Machines that have broken down will work perfectly when the repairman arrives.
