Metallic anti-ThCr2Si2-type RE2O2Bi (RE = rare earth) with Bi square nets show superconductivity while insulating La2O2Bi shows high hole mobility, by expanding the c-axis length through oxygen intercalation. In this...
Zr-doped CeO2 was used as a solid-state oxidant for topotactic oxidation. The topotactic oxidation was applied to anti-ThCr2Si2 type Y2O2Bi, which becomes superconducting via oxygen intercalation. In comparison with conventional...
