Black phosphorus, a two-dimensional layered material, is attracting attention as a next-generation nanodevice material, and although the possibility of relaxation near the surface of black phosphorus has been reported by DFT calculations, its surface structure seems to be poorly understood. In this study, we analyzed the structure of black phosphorus using photoelectron holography and compared the experimental images with simulations to observe the surface relaxation.
