Title:
HEAVILY DOPED PbSe WITH HIGH THERMOELECTRIC PERFORMANCE
Document Type and Number:
WIPO Patent Application WO/2012/058340
Kind Code:
A3
Abstract:
The present invention discloses heavily doped PbSe with high thermoelectric performance. Thermoelectric property measurements disclosed herein indicated that PbSe is high zT material for mid-to-high temperature thermoelectric applications. At 850 K a peak zT > 1.3 was observed when n
Η
~ 1.0x 1020 cm-3. The present invention also discloses that a number of strategies used to improve zT of PbTe, such as alloying with other elements, nanostructuring and band modification may also be used to further improve zT in PbSe.
