| 英文摘要 | Materials showing abrupt change of thermal conductivity are strongly desired for rapidly developing thermal regulation applications. Here, we report a sharp change of thermal conductivity (Delta kappa/kappa(0)) up to 200% within a temperature interval of similar to 40 K in hexagonal sulfides Ni1-xFexS bonded with silver. Such Delta kappa/kappa(0) values exceed those reported in other thermal regulation materials, e.g., VO2 series (Delta kappa/kappa(0)<100%). The large jump of thermal conductivity roots from the dramatic modification of the electronic structure at the first-order phase transition. Moreover, the addition of silver overcomes the inherent brittleness of Ni1-xFexS and thus improves machinability and thermal cycling stability, which is beneficial to the practical applications. Our work presents a new promising material for thermal management applications. (C) 2021 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved. |
