Integrating abnormal thermal expansion and ultralow thermal conductivity into (Cd,Ni)2Re2O7 via synergy of local structure distortion and soft acoustic phonons

Abnormal thermal expansion denotes intriguing negative and zero thermal expansion (NTE and ZTE). The integration of abnormal thermal expansion with low thermal conductivity is highly desirable for high-end devices.

The integration of abnormal thermal expansion with low thermal conductivity is highly desirable for high-end devices. However, the coexistence of seemingly contradictory features presents a grand challenge for abnormal-thermal-expansion materials. Herein, a unique NTE, for the first time, is reported in Cd2Re2O7 with a volumetric coefficient of thermal expansion, αV of -5.0 × 10−6/K (5 - 210 K). Moreover, a remarkable ZTE is attained in Cd1.95Ni0.05Re2O7 with αV of 1.1 × 10−6/K (5 - 180 K). Concomitantly, the attained ultralow thermal conductivities of 0.38 and 0.56 W/mK at 300 K of the two compositions are also highly competitive, exceeding prevailing abnormal-thermal-expansion materials. Concurrently, Cd2Re2O7-based oxides demonstrate orders of magnitude higher electrical conductivity than representative NTE materials. By a combined investigation of synchrotron X-ray techniques, aberration-corrected scanning transmission electron microscope, and phonon calculations, the synergy of local structure distortion highlighted by ordered Re-Re dimer and soft acoustic phonons is integral to the simultaneous accomplishment of distinctive thermal expansion and thermal conductivity, which is totally distinct from predominant optical-phonon driven NTE. This integration of intriguing thermal properties effectively resolves thermal issues and permits excellent size and temperature stability. This work opens up an unusual strategy to delicately control thermal expansion and thermal conductivity simultaneously.This work is supported by the Science Fund Program for Distinguished Young Scholars (Overseas), the National Natural Science Foundation of China (No. 22205171), 111 project 2.0 (BP2018008), the International Postdoctoral Exchange Fellowship Program (Talent-Introduction Program) and the China Postdoctoral Science Foundation (No. 2023M732754).
