UV-Induced Anisotropy In CdBr2-CdBr2: Cu Nanostructures

Isotropie and Anisotropie Nuclear Magnetic Shielding of 1 1 3Cd in Cadmiumhalides, Cadmiumchalcogenides and in Cadmiumcarbonate

The NMR signals of 113Cd have been observed in powder samples of the cadmium halides CdF,, CdCl2, CdBr2 '4H20, Cdl 2 , of the cadmium chalcogenides CdO, CdS, CdSe, CdTe and of CdC03 . For m C d in CdCl2 , CdBr2-4H20, CdS and in CdSe anisotropics of the nuclear magnetic shielding have been detected. The shielding tensor in these powders is axially symmetric. For the other specimens no anisotropi...

Magnetic Anisotropy and Exchange in (001) Textured FePt-based Nanostructures

Mapping the magnetic anisotropy in (Ga,Mn)As nanostructures

Anisotropic strain relaxation in Ga,Mn As nanostructures was studied combining time-resolved Kerr microscopy and ferromagnetic resonance techniques. Local resonance measurements on individual narrow stripes patterned along various crystallographic directions reveal that the easy axis of the magnetization can be forced perpendicular to the strain relaxation direction. Spatially resolved measurem...

Polarity-driven polytypic branching in cu-based quaternary chalcogenide nanostructures.

An appropriate way of realizing property nanoengineering in complex quaternary chalcogenide nanocrystals is presented for Cu2CdxSnSey(CCTSe) polypods. The pivotal role of the polarity in determining morphology, growth, and the polytypic branching mechanism is demonstrated. Polarity is considered to be responsible for the formation of an initial seed that takes the form of a tetrahedron with fou...

IR and UV Spectroscopic Analysis of C20 Carbon Nanostructures

Infrared (IR) and ultraviolet (UV) spectroscopic analysis of eight structural isomers of C20 carbon nanostructures, i.e. ring, tadpole, bow-tie, dumb-bell, spiro, propellane, bowl and cage, were performed at different levels of theory including semi-empirical (AM1 and PM3), Hartree-Fock (HF/6-31++G, 6-31++G**) and density functional theory (B3LYP/6-31++G, 6-31++G**). A broad range of IR spectra...
