Abstract
Quantum-dot superlattice (QLSL) structures having improved thermoelectric properties are described. In one embodiment, PbSe Te /PbTe QDSLs are provided having enhanced values of Seebeck coefficient and thermoelectric figure of merit (ZT) relative to bulk values. The structures can be combined into multi-chip devices to provide additional thermoelectric performance.
