摘要：new-joined 2d layered material - black phosphorus (bp), due to strong in-plane structural anisotropy, has exhibited exotic electrical, optical, and thermal properties while its thermal radiative properties are still largely unexplored. here, we investigate near-field thermal radiation of mono/multilayer bp, and find that monolayer bp can support three-order-of-magnitude enhanced heat exchange over blackbodies, even exceeding optimized graphene sheets by around 18.5%. we derive the dispersion relation of coupled anisotropic bp surface plasmon polaritons (spps), which is find to have a good agreement with the energy transmission contour of evanescent waves. the prominent thermal radiation rate thus can be attributed to the excitation of quasi-elliptic bp spps enabled by its unique structural anisotropy and doping. with increasing number of layers, near-field radiative heat flux decreases monotonously. the underlying mechanism lies in the increased imaginary part of optical conductivity but weak coupling with high-wavevector photons. this work helps elucidate the near-field thermal radiation mechanism of mono/multilayer bp, and paves the way for the application of emerging bp in non-contact thermal management and energy conversion.
