The impact of tensile biaxial strain on the thermal transport properties of hydrogen (HD), fluorine (FD), and chlorine (ClD) functionalized diamane is investigated by using the Boltzmann transport equation. Our results reveal ClD as an exceptionally strain-sensitive material for thermal transport applications, exhibiting a 70% reduction in thermal conductivity at a 5% strain—outperforming HD and FD. The strain-induced modifications in phonon dispersion and phonon scattering rates result in the unique responsiveness of ClD. This discovery positions ClD as a promising candidate for applications demanding highly tunable thermal conductivity. The ability to precisely control thermal properties makes ClD an ideal candidate for the development of thermal smart metamaterials, opening avenues for innovations in thermal management and diverse applications in the field of advanced materials.

揭示氯化二金刚烷的应变敏感热传输特性
利用玻尔兹曼输运方程研究了拉伸双轴应变对氢 (HD)、氟 (FD) 和氯 (ClD) 官能化二烷的热输运性能的影响。我们的结果表明,ClD 是一种用于热传输应用的异常应变敏感材料,在 5% 应变下导热系数降低 70%,优于 HD 和 FD。应变引起的声子色散和声子散射率的变化导致了 ClD 的独特响应性。这一发现使 ClD 成为需要高度可调热导率的应用的有希望的候选者。精确控制热性能的能力使 ClD 成为开发热智能超材料的理想候选者,为先进材料领域热管理和多样化应用的创新开辟了途径。
