An efficient method to introduce magnetic attributes to highly complex Au mesostructures by overlayer growth is demonstrated. The overlayer is nanostructured in all the cases investigated. A possible mechanism for the reduction of ions on the surface of Au mesoflowers and the consequent formation of hybrid mesoflowers is discussed. We studied the magnetic hysteresis behavior of Au/Ni, Au/Co, an...

Cyclic voltammetric surface waves were found for monolayers of Ru(bpy)Z(bpyY+, where bpy’ is 4-methyl4’-(dodecyl-l-thiol)-2,2’-bipyridine, which spontaneously adsorbs onto conducting substrates (indium tin oxide, polycrystalline gold). On polycrystalline gold, the monolayer, probably attached via the thiol functional group, is oxidized in an aqueous oxalate medium to produce electrogenerated ch...

It is offered to operate the transmittance of a diffraction mask by changing the interference properties of a thin optical layer. Based on the results of the offered approach the amplitude-phase diffraction grating with the period of 300 microns has been made from the 115 nm transparent indium tin oxide (ITO) film. Optical and dimensional parameters of the diffraction mask have been investigate...

This work is an extended version of a paper published previously [S. de Man et al., Phys. Rev. Lett. 103, 040402 (2009)], where we presented measurements of the Casimir force between a gold-coated sphere and a plate coated with either gold or an indium tin oxide (I TO) layer. The experiment, which was performed in air, showed that I TO conducts sufficiently to prevent charge accumulation but is...

In this paper, the fabrication and characterisation of pentacene-based photoconductors using indium tin oxide electrodes obtained by ion beam sputtering are discussed. The photoelectric properties of pentacene under red (632 nm) and ultraviolet (365 nm) illuminations were investigated. We have shown that the photocurrent was dependent on the wavelength, bias voltage and illumination side of the...

The initial growth mode of indium tin oxide on glass was studied. An interesting transition from a 3D island growth mode at low temperatures to 2D growth at higher temperature was observed. This transition from the Volmer-Weber mechanism to the Frank–van der Merwe mechanism occurs at about 150°C. It coincides with the transition from amorphous to polycrystalline growth of the thin films. © 1996...
