Absence of phonon gap driven ultralow lattice thermal conductivity in half-Heusler LuNiBi
Xiao-Xia Yu, Jiawang Hong
Abstract
LuNiBi is found to possess an ultralow thermal conductivity, two orders of magnitude smaller than the most of of half-Heuslers, promissing for the thermoelectric applications.
