Probing electrical transport properties of ultra-low thermal conductivity SnCr2S4 nanowhiskers
Résumé
The search for new and more sustainable ways of producing energy has led to the study of novel thermoelectric materials featuring high efficiency in the direct conversion of waste heat into electricity, for which novel materials are required to exhibit low thermal conductivity coupled with high electrical conductivity [1] . In this scenario, incommensurate chimney-ladder compounds [2] (e.g., SnCr 2 S 4 ) can be identified as a promising material class, owing to the expectations for their ultra-low thermal conductivity. However, to date their electric transport properties remain unveiled.
