Effects of Nonstoichiometry in a 3−x C 60 (a= K, Rb)
نویسنده
چکیده
We perform self-consistent Hartree calculations for a model of A 3−x C 60 (A= K, Rb) to study the effects of the presence of vacancies. We find that the strong vacancy potential is very efficiently screened and that the density of states is only weakly influenced by the presence of vacancies.

Nonstoichiometry of LixCu2O2+ single crystal and its relation to magnetic ordering
We report the first systematic study on the nonstoichiometry of Li/Cu ionic ratios x and oxygen defect concentrations in LixCu2O2+ solid solution. Nonstoichiometric crystals with intentional Li-deficient x=0.97 or Li-excessive x=1.06 concentrations were prepared by slow-cooling and floating-zone methods. By applying different oxygen pressures during growth, different magnitudes of oxygen defect...

Perovskite-type oxides of LaFe(1+x)O(3+δ) (x = 0.0, 0.2, 0.5 and 0.7) were synthesized by citrate sol–gel methodto ensure the formation of nanosized perovskites. The physicochemical properties of these LaFe(1+x)O(3+δ)materials were characterized by thermal gravimetric/differential analyses, Fourier transform infraredspectroscopy, X-ray powder diffraction, scanning electron and...

Let $X$ be a real normed space, then $C(subseteq X)$ is functionally convex (briefly, $F$-convex), if $T(C)subseteq Bbb R $ is convex for all bounded linear transformations $Tin B(X,R)$; and $K(subseteq X)$ is functionally closed (briefly, $F$-closed), if $T(K)subseteq Bbb R $ is closed for all bounded linear transformations $Tin B(X,R)$. We improve the Krein-Milman theorem ...

The Qohrud granitoid is a part of the Urmia-Dokhtar magmatic assemblage. The main rock types are Miocene granite and tonalite. The hydrothermal activities were effective due to intrusion. Hydrothermal activities were more intense in the southern part of the pluton. This has produced relatively large automorph quartz crystals. The alteration of the granitoid wall rocks was accompanied with alter...
