Role of the local structure in superconductivity of LaO0.5F0.5BiS2−xSex system

We have studied the local structure of LaO0.5F0.5BiS2−xSex by Bi L1-edge extended x-ray absorption fine structure (EXAFS). We find a significant effect of Se substitution on the local atomic correlations with a gradual elongation of average in-plane Bi-S bondlength. The associated mean square relati...
