Strong-correlation induced high-mobility electrons in Dirac semimetal of perovskite oxide, Published online: 21 January 2019; doi:10.1038/s41467-018-08149-y

Electron correlation normally makes electrons less mobile, but it is still not clear when correlation becomes very strong in Dirac semimetals. Here, Fujioka et al. report a very high electron mobility exceeding 60,000 cm2V−1s−1 in correlated Dirac semimetal of perovskite CaIrO3, due to the enhanced electron correlation nearby the Mott transition.
