近年来，通过实验合成的碳蜂窝结构因其力学强度大、热导率高、重量轻等特点受到了科学界广泛关注。在本工作中，我们利用非平衡分子动力学方法研究了近期提出的一种稳定碳蜂窝结构(hC28) 的热输运性质。结果表明，该结构沿蜂窝轴方向热导率远高于垂直于蜂窝轴方向的热导率，具有各向异性特征。此外，随着温度的升高，高阶声子间散射增强，模型的热导率逐渐降低。本文的研究结果对于开发碳蜂窝结构作为热传导器件具有一定的指导意义。

In recent years, carbon honeycomb structures synthesized by experiments have been widely concerned by the scientific community because of their high mechanical strength, high thermal conductivity and light weight. In this work, we investigate the heat transport properties of a recently proposed stable carbon honeycomb structure (hC28) using non-equilibrium molecular dynamics methods. The results show that the thermal conductivity along the honeycomb axis is much higher than that perpendicular to the honeycomb axis, showing anisotropy. In addition, with the increase of temperature, the scattering between higher order phonons is enhanced, and the thermal conductivity of the model decreases gradually. The research results of this paper have a certain guiding significance for the development of carbon honeycomb structure as a heat conduction device.
