Atomic Ordering in Cubic Bismuth Telluride Alloy Phases at High Pressure
I. Loa, J. -W. G. Bos, R. A. Downie +1
Pressure-induced transitions from ordered intermetallic phases to substitutional alloys to semi-ordered phases were studied in a series of bismuth tellurides. Using angle-dispersiv…
Structural Changes in Thermoelectric SnSe at High Pressures
I Loa, R J Husband, R A Downie +2
The crystal structure of the thermoelectric material tin selenide has been investigated with angle-dispersive synchrotron x-ray powder diffraction under hydrostatic pressure up to…
Glass-like thermal conductivity in SrTiO3 thermoelectrics induced by A-site vacancies
S. R. Popuri, A. J. M. Scott, R. A. Downie +5
The introduction of A-site vacancies in SrTiO3 results in a glass-like thermal conductivity while Nb substituted samples maintains good electrical conductivity. This unexpected res…
Enhanced thermoelectric performance in TiNiSn-based half-Heuslers
R. A. Downie, D. A. MacLaren, R. I. Smith +1
Thermoelectric figures of merit, ZT > 0.5, have been obtained in arc-melted TiNiSn-based ingots. This promising conversion efficiency is due to a low lattice thermal conductivity,…
Phase Stability, Structures and Properties of the (Bi2)m(Bi2Te3)n Natural Superlattices
J. -W. G. Bos, F. Faucheux, R. A. Downie +1
The phase stability of the (Bi2)m(Bi2Te3)n natural superlattices has been investigated through the low temperature solid state synthesis of a number of new binary BixTe1-x composit…
