High values of thermoelectric figures of merit ZT, ranging from ZT=1.6 at 300 K to ZT=3 at 550 K, are reported for Bi-doped n-type PbSeTe/PbTe quantum-dot superlattice (QDSL) samples grown by molecular beam epitaxy (MBE). These ZT values were determi

The thermoelectric properties of PbTe/Te superlattice structures grown by molecular beam epitaxy have been investigated. The in-plane Seebeck coefficient, Hall coefficient, and electrical resistivity have been measured at 300K. The data show that a s

Recently, it has been shown theoretically that it may be possible to increase the thermoelectric figure of merit ($Z$) of certain materials by preparing them in the form of two-dimensional quantum-well structures. Using $\mathrm{PbTe}/{\mathrm{Pb}}_{

Following the experimentally observed Seebeck coefficient enhancement in PbTe quantum wells in Pb/sub 1-x/Eu/sub x/Te/PbTe multiple-quantum-well structures which indicated the potential usefulness of low dimensionality, we have investigated the therm
