The homogeneous CuZnO and heterogeneous Ag/ZnO nanorods were synthesised by controlling the ionic radius of Cu and Ag with lattice of ZnO. The structure of CuZnO and Ag/ZnO was investigated by a series of methods. The study of the photoelectric properties suggested both the homogeneously and ...
The neighbouring divalent elements are and the facts about the crystal structures are: Monoxides: MnO, FeO, CoO, NiO, MgO, CdO, rock-salt structure: ZnO, wurtzite and zinc-blende structures. CuO has a quite different structure, very similar to that of PdO, with square co-ordination of the...
In ionic solids such as NaCl and ZnO, ions are in regular fixed arrangements with anions surrounded by cations and attracted to each other with electrostatic Coulombic forces of long range. The bonding is not localised and the whole solid is rather like a large molecule. Ionic solids also cont...
NCERT solutions for CBSE and other state boards is a key requirement for students. Doubtnut helps with homework, doubts and solutions to all the questions. It has helped students get under AIR 100 in NEET & IIT JEE. Get PDF and video solutions of IIT-JEE Mains & Advanced previous year pap...
and BCNPs systems, respectively. In a mixed system, the Hamaker constants were estimated as their arithmetic mean. r1and r2are the hydrodynamic radius of nanoparticles, h is the separation distance between nanoparticles, and λ is the characteristic wavelength of interaction (100 nm) (Gregory1981)...
The spin-orbit couplings in the valence bands of the zincblende and wurtzite structures such as cuprous halides and ZnO are investivigated in the tight-binding approximation. It is shown that the d-orbital of the cation contributes a neg... K Shindo,A Morita,H Kamimura - 《Journal of the...

S1. As the ionic radius of Li+ in the octahedral environment (0.76 Å) is larger than the radii of other ions present in the system (assuming their +2 charge state), the observed decrease of the lattice parameter (Fig. 2) needs a more detailed explanation. The unit cell shrinkage is...
17,18,26 where the exchange-correlation potential of small systems in the continuum was calculated. These computations have shown that the jump due to the addition of a small but finite fractional charge 0 , f , 1 is spatially constant inside a region of radius R around the bound charges ...
