摘要：
We are continuing our synthetic investigations in the ternary A/Bi/Se systems and also expanded our interests into the quaternary A/M/Bi/Se (A = Rb, Cs, Sr and Ba; M = lanthanide or Pb) systems. We have synthesized several new ternary and quaternary bismuth selenides with band gaps <0.6eV such as CS2Bi7.33Se12, A(2)Bi(8)Se(13) (A = Rb, Cs), Ba4-xBi6+2/3xSe13, and Ba3+/-xPb3+/-xBi6Se15. The synthesis, crystal structures and charge transports properties of these new compounds are presented.
