Electrons “synch up” to form superconductors

Facebook X LinkedIn Email
One hundred years after superconductivity was first observed in 1911, a team of researchers has used laser light to transform a nonsuperconducting material into a superconductor. Superconductivity – a phenomenon in which an electric current travels through a material without any resistance – allows materials to act as perfect electrical conductors without any energy loss. The researchers, from Oxford, Germany and Japan, observed conclusive signatures of superconductivity after hitting a nonsuperconductor with a strong burst of laser light. They used a material closely...Read full article

    superconductor
    A metal, alloy or compound that loses its electrical resistance at temperatures below a certain transition temperature referred to as Tc. High-temperature superconductors occur near 130 K, while low-temperature superconductors have Tc in the range of 4 to 18 K.
