    Plots of Seebeck coefficient vs the logarithm of electrical conductivity (Jonker plots) can be used to discriminate small polaron from band-type semiconductivity. Furthermore n-type and p-type small polaron conduction can be discriminated. Examples are drawn from systems exhibiting extensive nonstoichiometry, e.g., CeO2-x and Fe1-xO, systems involving extensive doping, e.g., LaCro3:Sr and Mn3O4: Fe, and systems with extensive solid solubility, e.g., the spinel ferrites. Capabilities and limitations of the analysis are discussed.
