| 1 | Structural and mechanical stability of rare-earth diborides显示文摘Structural and mechanical properties of several rare-earth diborides were systematically investigated by first principles calculations. Specifically, we studied XB2 , where X=Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, and Lu in the hexagonal AlB2 , ReB2 , and orthorhombic OsB2 -type structures. The lattice parameters, bulk modulus, bond distances, second order elastic constants, and related polycrystalline elastic moduli (e.g., shear modulus, Young's modulus, Poisson's ratio, Debye temperature, sound velocities) were calculated. Our results indicate that these compounds are mechanically stable in the considered structures, and according to 'Chen's method', the predicted Vickers hardness shows that they are hard materials in AlB2 - and OsB2 -type structures. | Haci Ozisik Engin Deligoz Kemal Colakoglu Gokhan Surucu | 2013 | Chinese Physics B2013，22，4： | 4 |
| 2 | First-principles study of the structural,elastic,electronic,optical,and vibrational properties of intermetallic Pd_2Ga显示文摘The structural,elastic,electronic,optical,and vibrational properties of the orthorhombic Pd2Ga compound are investigated using the norm-conserving pseudopotentials within the local density approximation in the frame of density functional theory.The calculated lattice parameters have been compared with the experimental values and found to be in good agreement with these results.The second-order elastic constants and the other relevant quantities,such as the Young's modulus,shear modulus,Poisson's ratio,anisotropy factor,sound velocity,and Debye temperature,have been calculated.It is shown that this compound is mechanically stable after analysing the calculated elastic constants.Furthermore,the real and imaginary parts of the dielectric function and the optical constants,such as the optical dielectric constant and the effective number of electrons per unit cell,are calculated and presented.The phonon dispersion curves are derived using the direct method.The present results demonstrate that this compound is dynamically stable. | Yildirim A Koc H Deligoz E | 2012 | Chinese Physics B2012，21，3： | 2 |
