Superconducting Transition Temperature of the Organic Alloy System. κ-[(BEDT-TTF)1−x(BEDT-STF)x]2Cu[N(CN)2]Br

Abstract
The superconducting transition temperature (Tc) was investigated by alloying (BEDT-TTF)2Cu[N(CN)2]Br with (BEDT-STF)2Cu[N(CN)2]Br. The Tc of the former rapidly decreased with doping the latter. The relation between stoichiometry and structure is also discussed.
