The anisotropic thermal conductivity of passivated black phosphorus (BP), a reactive two-dimensional material with strong in-plane anisotropy, is ascertained. The room-temperature thermal conductivity for three crystalline axes of exfoliated BP is measured by time-domain thermo-reflectance. The thermal conductivity along the zigzag direction is ≈2.5 times higher than that of the armchair direction.
本研究测定了具有强面内各向异性的反应二维材料黑磷（BP）的各向异性热导率。通过时域热反射法测量了剥离 BP 的三个晶轴在室温下的热导率。锯齿形方向的热导率约为扶手椅方向的 2.5 倍。
