Title: Thermoelectric generators that incorporate self-segmenting thermoelectric legs

Abstract: The contact members used with thermoelectric legs formed from self-segmenting thermoelectric compositions (compositions in which a constituent migrates under the influence of combined thermal and electrical gradients to create a gradation of doping levels that is beneficial for thermoelectric conversion) should be specially chosen to compensate for and best take advantage of the self-segmenting feature. In general, at least an exterior thickness of the contact member against the end of the leg toward which the migrating constituent moves should include the constituent at substantially its free-state chemical potential.
