    Boron Carbides As Thermo-electric Materials (1988)
    In:  Other Sources
    Details
    Publication Date: 2019-07-12
    Description: Report reviews recent theoretical and experimental research on thermoelectric materials. Recent work with narrow-band semiconductors demonstrated possibility of relatively high thermoelectric energy-conversion efficiencies in materials withstanding high temperatures needed to attain such efficiencies. Among promising semiconductors are boron-rich borides, especially boron carbides.

    Advances In Thermoelectric Materials (1987)
    In:  Other Sources
    Details
    Publication Date: 2019-07-12
    Description: Rare-earth chalcogenides and boron-rich borides show promise. Report discusses search for materials performing more efficiently in high-temperature thermoelectric conversion. Begins with summary of developments during past three decades. Followed by brief introduction to theory of thermoelectric energy conversion, then by experimental findings and by some additional theory on specific materials.
