  We have synthesized a new layered BiS$_{2}$-based compound SrFBiS2. This
compound has similar structure to BiS2. It is built up by stacking up SrF
layers and NaCl-type BiS2 layers alternatively along the c axis. Electric
transport measurement indicates that SrFBiS2 is a semiconductor. Thermal
transport measurement shows that SrFBiS2 has a small thermal conductivity and
large Seebeck coefficient. First principle calculations are in agreement with
experimental results and show that SrFBiS2 is very similar to LaOBiS2 which
becomes superconductor with F doping. Therefore, SrFBiS2 may be a parent
compound of new superconductors.
