摘要
Abstract Single crystals of the 2-D layered host SnS 2−x Se x (x = 0, 0.3, 0.5, 1.3, 1.85 and 2) have been intercalated with cobaltocene {Co(ν-Cp) 2 ; Cp = C 5 H 5 }. The host materials are all semiconductors with activation energy (E a ) varying from 0.02 – 0.45 eV. The intercalates are all ca . 2 × 10 2 less resistive than the hosts, and the temperature dependence of their resistivities range from variable range hopping (VRH) semiconductors to superconductors [Tc = 6.1 K for SnSe 2 {Co( ν -Cp) 2 }0.3].
