Electrodeposition of flattened Cu nanoclusters on a p-GaAs(001) electrode monitored by in situ optical second harmonic generation
Article Abstract:
In situ optical second harmonic generation (SHG) technique was employed to investigate the shape and density of Cu nanoclusters, which were electrochemically formed on p-GaAs(001) electrode surfaces. The results showed that the SHG signal at the present optical geometry was sensitive to the number of oblate or flattened Cu nanoclusters with lateral diameter larger than 30 nm and that the SHG enhancement occurred because of resonant coupling between the surface plasmon induced in the flattened Cu nanoclusters and the near-infrared fundamental light.

The X-ray diffraction patterns of bimetallic Fe(sub x)M(sub 100-x) (M = Mo and W) nanoclusters
Article Abstract:
The study produces the equilibrium phase Fe(sub x)m(sub 100-x) and Fe(sub x)W(sub 100-x) nanoclusters by thermally decomposing two metal carbonyl vapor species and investigated structures by recording the XRD patterns. It is observed that the solubilities of Fe(sub x)m(sub 100-x) and Fe(sub x)W(sub 100-x) nanoclusters were lower than those of the corresponding nonequilibrium phase bimetallic nanoclusters and alloys.

Simulation and interpretation of 2D diffraction patterns from self-assembled nanostructured films at arbitrary angles of incidence: From grazing incidence (above the critical angle) to transmission perpendicular to the substrate
Article Abstract:
The development of theory and simulation code, called NANOCELL, to model diffraction spot patterns from ordered and oriented periodic nanostructured films for any angle of incidence above the critical angle of the film is reported. NANOCELL is used to simulate and interpret the two dimensional (2D) scattering patterns typically observed from self-assembled nanostructured films.
