Journal ArticleDOI
Rapid hydrothermal synthesis of VO2 (B) and its conversion to thermochromic VO2 (M1)
S. R. Popuri,M. Miclau,Alla Artemenko,Alla Artemenko,Christine Labrugère,Antoine Villesuzanne,Antoine Villesuzanne,M. Pollet,M. Pollet +8 more
TL;DR: The present study shows that phase-pure VO2 (B) polytype can be easily obtained at 180 °C for 2 h and 220 ° C for 1 h, that is, the lowest combination of temperature and duration reported so far.
Journal ArticleDOI
Large thermoelectric power factors and impact of texturing on the thermal conductivity in polycrystalline SnSe
S. R. Popuri,Michaël Pollet,Michaël Pollet,Rodolphe Decourt,Rodolphe Decourt,Finlay D. Morrison,Nick Bennett,Jan-Willem G. Bos +7 more
TL;DR: In this paper, the authors reported on the synthesis of highly textured polycrystalline SnSe ingots with large single-crystal magnitude power factors, S2/ρ = 0.2-0.5.
Journal ArticleDOI
Facile Surfactant-Free Synthesis of p-Type SnSe Nanoplates with Exceptional Thermoelectric Power Factors
Guang Han,S. R. Popuri,Heather F. Greer,Jan-Willem G. Bos,Wuzong Zhou,Andrew Ramsay Knox,Andrea Montecucco,Jonathan Siviter,Elena A. Man,Martin W. S. Macauley,Douglas J. Paul,Wenguang Li,Manosh C. Paul,Min Gao,Tracy K. N. Sweet,Robert Freer,Feridoon Azough,Hasan Baig,Nazmi Sellami,Tapas K. Mallick,Duncan H. Gregory +20 more
TL;DR: The surfactant‐free solution methodology, simply using water as a solvent, has been developed for the straightforward synthesis of single‐phase orthorhombic SnSe nanoplates in gram quantities, and offers an energy‐efficient, rapid route to p‐type Sn Se nanostructures.
Journal ArticleDOI
Glass-like thermal conductivity in SrTiO3 thermoelectrics induced by A-site vacancies
S. R. Popuri,A. J. M. Scott,R. A. Downie,M. A. Hall,E. Suard,Rodolphe Decourt,M. Pollet,Jan-Willem G. Bos +7 more
TL;DR: In this paper, the A-site vacancies in SrTiO3 results in a glass-like thermal conductivity while Nb substituted samples maintains good electrical conductivity, which brings the material one step closer to being a high-performing phonon-glass electron-crystal thermoelectric material.
