Transition temperatures to superconductivity.
(a) Temperature-dependent resistances of (PbSe)1.14(NbSe2)n ferecrystals measured in one of the van der Pauw measurement configurations, using the lock-in technique and normalized to the resistance at T = 4 K. (b) Superconducting transition temperatures Tc for (PbSe)1.14(NbSe2)n ferecrystals, MLCs and NbSe2 single crystals. Data for bulk (PbSe)1+x(NbSe2)n MLC single crystals are reported by Nader et al.20, Auriel et al. 199221, Auriel et al. 199323 and Auriel et al. 199529. Reports on Tc by Oosawa et al. are for pressed pelletized MLCs24. For NbSe2 mono-, bi- and trilayers (n = 1, 2, 3) Tc is given as reported by Xi et al.1 and for bilayers it is reported by Tsen et al.13.
