Abstract

Black phosphorus (BP) has emerged as a direct bandgap semiconducting material with great application potentials in electronics, photonics, and energy conversion. Experimental characterization of the anisotropic thermal properties of BP at the micrometer scale is extremely challenging. This study reports measurement results of the anisotropic thermal conductivity of BP along three primary crystalline orientations, using a novel time‐resolved magneto‐optical Kerr effect. The thermal conductivity along the zigzag crystalline direction is 84–101 W m−1 K−1, nearly three times as large as that along the armchair direction (26–36 W m−1 K−1). The through‐plane thermal conductivity of BP ranges from 4.3 to 5.5 W m−1 K−1. This study performs first‐principles calculation to predict the phonon transport in BP along both in‐plane through‐plane directions, and identifies that the strong anisotropy of thermal transport in BP can be attributed to the structural‐asymmetry‐induced group velocity variations along different crystalline orientations, and the relaxation time variation induced by the direction of the applied temperature gradient. This work successfully unveils the fundamental mechanisms of anisotropic thermal transport along the three crystalline directions in BP, as demonstrated by the excellent agreement between the first‐principles‐based theoretical predictions and experimental characterizations on the anisotropic thermal conductivities of BP.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
