“…Interestingly, not only are the electrical properties of BP anisotropic, but the different symmetries in the armchair (AC) and the ZZ‐directions also cause a large anisotropy in the phonon thermal conductivity. This was predicted theoretically and proven experimentally both in the few‐layer phosphorene limit as well as for thin films and bulk samples . With higher quality samples, the anisotropy ratio was seen to be ≈2 at all temperatures where the ZZ‐direction has a larger thermal conductivity than the AC‐direction for all samples, as shown in Figure .…”

“…With higher quality samples, the anisotropy ratio was seen to be ≈2 at all temperatures where the ZZ‐direction has a larger thermal conductivity than the AC‐direction for all samples, as shown in Figure . The difference in the absolute values could be attributed to different levels of defect density in BP, but the overall physics is identical in all these measurements. These measurements were all performed on undoped as‐obtained crystals of BP and hence the electrical measurements of optimally doped samples remain challenging.…”

“…[32] When p = 0, S(L) becomes Here, we assume the boundary acts as a diffuse scatterer that reradiates phonons in a random direction (p = 0), which has been done in the κ calculations of thin black phosphorus flakes due to the presence of surface disorder.…”

In‐Plane Anisotropic Thermal Conductivity of Few‐Layered Transition Metal Dichalcogenide Td‐WTe₂

et al. 2018

2D Td-WTe 2 has attracted increasing attention due to its promising applications in spintronic, field-effect chiral, and high-efficiency thermoelectric devices. It is known that thermal conductivity plays a crucial role in condensed matter devices, especially in 2D systems where phonons, electrons, and magnons are highly confined and coupled. This work reports the first experimental evidence of in-plane anisotropic thermal conductivities in suspended Td-WTe 2 samples of different thicknesses, and is also the first demonstration of such anisotropy in 2D transition metal dichalcogenides. The results reveal an obvious anisotropy in the thermal conductivities between the zigzag and armchair axes. The theoretical calculation implies that the in-plane anisotropy is attributed to the different mean free paths along the two orientations. As thickness decreases, the phonon-boundary scattering increases faster along the armchair direction, resulting in stronger anisotropy. The findings here are crucial for developing efficient thermal management schemes when engineering thermal-related applications of a 2D system.

“…The thermal conductivity of single‐layer phosphorene and bulk BP were investigated theoretically by independent groups using various methods . Besides the theoretical calculations, there are also reports on the thermal conductivity of phosphorene films and bulk BP from experimental measurements . Due to the limitations of the synthesis technique, only the results of phosphorene films with thickness ranging from 9.5 to 552 nm are available .…”

Phosphorene, a novel elemental 2D semiconductor, possesses fascinating chemical and physical properties which are distinctively different from other 2D materials. The rapidly growing applications of phosphorene in nano/optoelectronics and thermoelectrics call for comprehensive studies of thermal transport properties. In this Review, based on the theoretical and experimental progresses, the thermal transport properties of single-layer phosphorene, multilayer phosphorene (nanofilms), and bulk black phosphorus are summarized to give a general view of the overall thermal conductivity trend from single-layer to bulk form. The mechanism underlying the discrepancy in the reported thermal conductivity of phosphorene is discussed by reviewing the effect of different functionals and cutoff distances on the thermal transport evaluations. This Review then provides fundamental insight into the thermal transport in phosphorene by reviewing the role of resonant bonding in driving giant phonon anharmonicity and long-range interactions. In addition, the extrinsic thermal conductivity of phosphorene is reviewed by discussing the effects of strain and substrate, together with phosphorene based heterostructures and nanoribbons. This Review summarizes the progress of thermal transport in phosphorene from both theoretical calculations and experimental measurements, which would be of significance to the design and development of efficient phosphorene based nanoelectronics.
