Stability and mechanical properties of various Hf–H phases: A density-functional theory study Project supported by the National Natural Science Foundation of China (Grant Nos. 51401030 and 51504033). |
(color online) Comparison of densities of states of (a) the HCP Hf2 phase and (b) HCP(T), and (c) HCP(O) Hf2H phases. The red and blue curves represent H-s and Hf-d DOS, respectively. The Fermi energy is shifted to 0 eV. |
