The ordinary graphite in pencil lead is proving to be surprisingly multifaceted at the microscale.  In a study appearing today in the journal Nature, MIT researchers report that a certain microscopic structure found in natural graphite can host multiple superconducting states. Superconductivity is an electronic state of matter in which electrons pair up and glide […] The post Graphene can hold multiple states of superconductivity, a new study finds appeared first on MIT Physics .
