n-type as well as p-type semiconduction occurs in both "123" and "214" classes of oxide superconductors at elevated temperatures (600-850°C) as exhibited in plots of thermoelectric coefficient vs. logarithm of conductivity (Jonker plots). The similarity in high conductivity intercepts indicates similar conduction parameters (density-of-states, mobility) regardless of material or sign of charge carrier. The Jonker plot is a useful means of investigating the gradual transition from semiconducting to metallic behavior in these systems.
