摘要：
Single crystal growth and superconducting properties of LaO0.5F0.5BiSe2 are studied. Single crystals of LaO0.5F0.5BiSe2 were grown by a CsCl-flux method. Electrical resistivity rho(T) measurements were performed to elucidate its superconducting properties. The rho(T) shows metallic behavior and superconducting transition at 4.0 K. From rho(T) measurements in several magnetic fields, upper critical fields H-c2(vertical bar vertical bar ab)(0) and H-c2(c)(0) are estimated to be 7.05 T and 0.52 T, respectively. The superconducting anisotropic parameter Gamma is determined to be 13.6.
