Ta Melting Point Calculation by Small-cell Coexistence Method
(2014-08-16)We calculate the melting temperature of Tantalum, by employing the small-size coexistence solid-liquid coexistence method. Two pseudo-potentials are employed, namely Ta_v (5d^3 6s^2) and Ta_pv (5p^6 5d^3 6s^2). Results ... -

Li-Ni-Mn-Co-Ti-O Voltage Profile
(2014-08-11)The performance enhancements associated with Ti substitution of Co in the layered cathode material Li1(NixMnxCo1-2x)O2 were investigated using density functional theory calculations. Examining the structural and electronic ... -
GeTe-PbTe PbS-PbTe PbSe-PbS PbTe-PbSe PbTe-SnTe SnTe-GeTe mixing and coherency strain energies
(2012-10-15)Nanostructures formed by phase separation improve the thermoelectric figure of merit in lead chalcogenide semiconductor alloys, with coherent nanostructures giving larger improvements than incoherent nanostructures. However, ... -
Electronic structures of long periodic stacking order structures in Mg: A first-principles study
(2014-08-08)Long period stacking order (LPSO) structures, such as 6H, 10H, 14H, 18R and 24R, play significant roles in enhancing the mechanical properties of Mg alloys and have been largely investigated separately. In the present ... -
Elemental vacancy diffusion for fcc and hcp structures
(2014-08-08)This work demonstrates how databases of diffusion-related properties can be developed from high-throughput ab initio calculations. The formation and migration energies for vacancies of all adequately stable pure elements ... -
A Modified Embedded Atom Method Potential for the Titanium-Oxygen System
(2014-07-15)These data files correspond to our publication listed above. The files included here are: 1) LAMMPS and VASP input files describing the structures specified in the article. 2) LAMMPS and VASP output files describing the ... -
ZrSiO4-HfSiO4
(2013-05-09)ZrSiO4 and HfSiO4 are of considerable interest because of their low thermal expansions, thermal conductivities, and the optical properties of HfSiO4. In addition, silicate phases of both are studied as model radioactive ... -
In–Eu and In–Yb Thermodynamic assessments
(2013-07-08)Based on the experimental data including thermodynamic properties and phase equilibria, thermodynamic assessments of the In–Eu and In–Yb binary systems have been carried out by using the CALPHAD (Calculation of Phase ... -
Ag–Cd and Ag–Sn diffusion and atomic mobilities
(2013-07-08)Diffusion in Ag-based solders is a practical topic that has attracted world-wide attention. With the available experimental data in the literature, the atomic mobilities of Ag, Cd and Sn in fcc Ag–Cd and Ag–Sn alloys are ... -
Ti-O-M interaction between oxygen and metal (M) substitution in titanium for oxygen diffusion change
(2013-05-28)We calculate first-principles interaction energies between substitutional solutes and oxygen interstitials in α-titanium and predict the effect of solutes on oxygen diffusion from those interactions. Interaction between ... -
TiO2: On the possibility of ferromagnetism
(2013-04-08)To see if ferromagnetism can occur in C-doped anatase TiO2, we performed first-principles calculations for a number of C-doped structures in which C atoms substitute O atoms. Our study shows that each C has spin-polarized ... -

PbTiO3: Dipole moment of a Pb-O vacancy pair
(2013-04-08)The polarization of a nearest-neighbor (nn) Pb-O vacancy pair [(VPb-VO)nn] in PbTiO3 is calculated, using the modern theory of polarization, implemented in the density-functional-theory ultrasoft pseudopotential formalism. ... -
SiC-AlN, SiC-GaN and SiC-InN: wurtzite-structure quasibinary systems
(2013-04-08)The cluster-expansion method was used to perform first principles phase diagram calculations for the wurtzite-structure quasibinary systems (SiC)1-X(AlN)X, (SiC)1-X (GaN)X and (SiC)1-X(InN)X; and to model variations of ... -
NaNbO3–KNbO3: Can spinodal decomposition generate relaxor ferroelectricity?
(2013-04-08)First principles based phase diagram calculations were performed for the system (1−X) NaNbO3–(X) KNbO3. Plane wave pseudopotential calculations of formation energies were used as a basis for fitting a cluster expansion ... -
NaCl–KCl: The role of excess vibrational entropy
(2013-04-08)First principles phase diagram calculations were performed for the system NaCl–KCl. Plane-wave pseudopotential calculations of formation energies were used as a basis for fitting cluster expansion Hamiltonians, both with ...
