Query: Electronic phase diagram in the new BiS2-based Sr1-xLaxFBiS2 system   In this paper, we systematically study the electron doping effect in a new
BiS2-based system Sr1-xLaxFBiS2(0<x<0.7) through multiple techniques of X-ray
diffraction, electrical transport, magnetic susceptibility, and Hall effect
measurements. The parent compound SrFBiS2 is found to possess a
semiconducting-like ground state, with thermally activation energy Eg=38 meV.
By the partial substitution of La for Sr, superconductivity emerges when x >
0.3, reaching its maximal superconducting transition temperature Tc=3.5 K at
x=0.55. In the normal state of superconducting samples, it is clearly seen that
there exists a crossover from metallic to semiconducting state below a
temperature Tmin, which shifts to lower temperatures with increasing La
content. Based on these measurements, the associated electronic phase diagram
of Sr1-xLaxFBiS2 system has thus been established.
