摘要: Using first-principle calculations, we investigate the mechanical, structural, and electronic properties and formation energy of 25 kinds of Ⅲ-V binary monolayers in detail. A relative radius of the binary compound according to the atomic number in the periodic table is defined, and based on the definition, the 25 kinds of Ⅲ-V binary compounds are exactly located at a symmetric position in a symmetric matrix. The mechanical properties and band gaps are found to be very dependent on relative radius, while the effective mass of holes and electrons are found to be less dependent. A linear function between Young's modulus and formation energy is fitted with a linear relation in this paper. The change regularity of physical properties of B-V (V=P, As, Sb, Bi) and -N (=Al, Ga, In, Tl) are found to be very different from those of other Ⅲ-V binary compounds.
