By employing density functional and many-body perturbation theories, we explore the geometrics, quasiparticle band structure, and optical response of two-dimensional arsenic phosphorus (alpha-AsxP1-x). Calculations indicate that the alpha-AsxP1-x, exhibits excellent stability at high temperature. The quasi-particle bandgap of alpha-AsxP1-x is highly tunable in a broad range of 1.54-2.14 eV depending on the composition. The optical absorption of alpha-AsxP1-x, can cover the visible and ultraviolet regions, and is highly anisotropic. More interestingly, it is tunable to optical absorption of alpha-AsxP1-x when the composition continuously increased. Also, they have sizable exciton binding energies. These findings suggest that alpha-AsxP1-x holds great potentials for applications in high-performance electronics and optoelectronics.
