标题： Anisotropic Thermal Conductivity of Exfoliated Black Phosphorus

摘要： 我们确定了氧化铝钝化黑磷（BP）的各向异性热导率，这是一种具有强平面内各向异性的反应性二维纳米材料。 我们通过时域热反射法测量了剥离黑磷的三个晶体轴的室温热导率。 沿锯齿形方向的热导率（86 +/- 8 W/(m*K)）约为扶手椅方向（34 +/- 4 W/(m*K)）的2.5倍。 显示英文摘要

摘要： We ascertain the anisotropic thermal conductivity of alumina passivated black phosphorus (BP), a reactive 2D nanomaterial with strong in-plane anisotropy. We measure the room temperature thermal conductivity by time-domain thermoreflectance for the three crystalline axes of exfoliated BP. The thermal conductivity along the zigzag direction (86 +/- 8 W/(m*K)) is ~2.5 times higher than that of the armchair direction (34 +/- 4 W/(m*K)).
