Structures, phase transition, elastic properties of SnO2 from first-principles analysis
چکیده انگلیسی

We investigate the structural, phase transition and elastic properties of SnO2 in the rutile-type, pyrite-type, ZrO2-type and cotunnite-type phases by the plane-wave pseudopotential density functional theory method. The lattice constants, bulk modulus and its pressure derivative are well consistent with the available experimental and other theoretical data. Also, we find that the rutile→pyrite, pyrite→ZrO2 and ZrO2→cotunnite phase transition occur at 12.9, 59.1 and 111.1 GPa, which are in better agreement with the experimental results than those of Gracia et al. (2007). Moreover, we obtain the pressure dependences of elastic constants for the four structures.
