| 2 | Mechanical and thermodynamical stability of BiVO4 polymorphs using first-principles study显示文摘First principles calculations of structural, electronic, mechanical, and thermodynamic properties of different polymorphs of BiVO_4 are performed using Bender-type plane/wave ultrasoft pseudopotentials within the generalized gradient approximation(GGA) in the frame of density functional theory(DFT). The calculated structural and electronic properties are consistent with the previous theoretical and experimental results. The electronic structures reveal that m-BiVO_4, opBiVO_4, and st-BiVO_4 have indirect band gaps, on the other hand, zt-BiVO_4 has a direct band gap. From the DOS and Mulliken's charge analysis, it is observed that only m-BiVO_4 has 6s^2Bi lone pair. Bond population analysis indicates that st-BiVO_4 shows a more ionic nature and a similar result is obtained from the elastic properties. From the elastic properties, it is observed that st-BiVO_4 is more mechanically stable than the others. st-BiVO_4 is more ductile and useful for high electro-optical and electro-mechanical coupling devices. Our calculated thermodynamic properties confirm the similar characteristics found from electronic and elastic properties. m-BiVO_4 is useful as photocatalysts, solid state electrolyte,and electrode and other polymorphs are applicable in electronic device fabrications. | A K M Farid UI Islam Md Nurul Huda Liton H M Tariqul Islam Md Al Helal Md Kamruzzaman | 2017 | Chinese Physics B2017，26，3： | 0 |
