Contrasted Sn Substitution effects on Dirac line node semimetals SrIrO$_{3}$ and CaIrO$_{3}$

13 Nov 2019 Negishi Masamichi Hiraoka Naoka Nishio-Hamane Daisuke Takagi Hidenori

Perovskite-type iridates SrIrO$_{3}$ and CaIrO$_{3}$ are a Dirac line node semimetal protected by crystalline symmetry, providing an interesting playground to investigate electron correlation effects on topological semimetals. The effect of Sn doping was examined by growing SrIr$_{1-x}$Sn$_{x}$O$_{3}$ and CaIr$_{1-x}$Sn$_{x}$O$_{3}$ thin films epitaxially on SrTiO$_{3}$(001) substrate using pulsed laser deposition...
