Autor: Zezhu Zeng, Xingchen Shen, Ruihuan Cheng, Olivier Perez, Niuchang Ouyang, Zheyong Fan, Pierric Lemoine, Bernard Raveau, Emmanuel Guilmeau, Yue Chen
Publikováno v: Nature Communications, Vol 15, Iss 1, Pp 1-9 (2024)
Abstract Materials with low thermal conductivity usually have complex crystal structures. Herein we experimentally find that a simple crystal structure material AgTlI2 (I4/mcm) owns an extremely low thermal conductivity of 0.25 W/mK at room temperatu

Synthesis and Thermoelectric Properties in the 2D Ti1 – xNbxS3 Trichalcogenides
Autor: Patrick R. N. Misse, David Berthebaud, Oleg I. Lebedev, Antoine Maignan, Emmanuel Guilmeau
Publikováno v: Materials, Vol 8, Iss 5, Pp 2514-2522 (2015)
A solid solution of Ti1 − xNbxS3 composition (x = 0, 0.05, 0.07, 0.10) was synthesized by solid-liquid-vapor reaction followed by spark plasma sintering. The obtained compounds crystallize in the monoclinic ZrSe3 structure type. For the x = 0.07 sa
