Stoichiometric cerium oxide nanoparticles with different sizes, ranging between 2 and 12 nm, were prepared by a rational design of the synthetic concept, based on a special hydrothermal procedure. ...

Since there are still research interests in the physical properties of quasi-binary thermoelectric [Formula: see text] alloys, with X, Y = Si, Ge, Sn, we present an ab initio analysis that yields the relative formation energy and effective masses of

${\mathrm{Mg}}_{2}{X}_{1\ensuremath{-}x}{Y}_{x}$ thermoelectric materials and their pseudobinary related alloys, for $X,Y$ = Si,Ge,Sn, have been the subject of intense research activity. Studies have revealed their electronic nature, but important pr

We present density functional theory (DFT) calculations on phonon dispersions, phonon density of states, and thermodynamic quantities for the three copper oxide phases ${\mathrm{Cu}}_{2}\mathrm{O},{\mathrm{Cu}}_{4}{\mathrm{O}}_{3}$, and CuO. For mono

The existence of an intermediate phase of tin oxide was first reported in 1882. However, its stoichiometry and its crystal structure have been dubious and heavily debated ever since, despite a multitude of structural investigations. We show that Rama

We analyze the influence of the Mg concentration on several important properties of the band structure of Zn1-xMgxO alloys in wurtzite structure using ab initio calculations. For this purpose, the band structure for finite concentrations is defined i

We perform density functional theory calculations to determine equilibrium lattice parameters of wurtzite Zn1-xMgxO alloys for Mg concentrationsxranging from 0 to 31.25 %. We use the local density approximation (LDA) as well as the generalized gradie
