Superconductivity induced by electron doping in the system La1-xMxOBiS2 (M = Ti, Zr, Hf, Th)

D. Yazici, K. Huang, B. D. White +7

We report a strategy to induce superconductivity in the BiS${}_2$-based compound LaOBiS${}_2$. Instead of substituting F for O, we increase the charge-carrier density (electron dope) v…
