摘要：Recently, a new monoclinic P2(1)/m phase of Rh2B and RhB2 was predicted, which is energetically superior to the experimentally proposed Pnma phase. For the new phase, we studied the high-pressure structural and elastic properties of Rh2B and RhB2 by using first-principles calculations. A complete elastic tensor and crystal anisotropies of P2(1)/m-Rh2B and P2(1)/m-RhB2 are determined. Additionally, the electronic density of states, bulk modulus, shear modulus, Young's modulus, Poisson's ratio, and elastic anisotropy factor were discussed in detail.
