The interest behind most SPM studies of silver thin films on mica has been the desire to obtain metal films for use as substrates in other studies.

These SPM studies show a variety of silver thin film morphologies at various locations in the parameter space. Buchholz et al. found the best results at °C. They also found that above °C the Cited by: STM studies of laser-induced effects on rough silver films François Blais, M.

We review our recent studies of photochemistry and plasmon chemistry of dimethyl disulfide, (CH 3 S) 2, molecules adsorbed on metal surfaces using a scanning tunneling microscope (STM).The STM has been used not only for the observation of surface structures at atomic spatial resolution but also for local by: 3.

Pt, Pd, and Rh films of a few nanometers in thickness supported on glassy carbon (GC) and other substrates were prepared by electrochemical voltammetry. STM patterns illustrated that the prepared thin films are composed of crystallites of layer structure and exhibit a low surface roughness.

A rather rough structure was developed on the normal film after shots (Fig. 4a.1) while the surface of the filled sample proved to be much finer with some cones (Fig. 4b.1). After pulses the conical structure appeared on the surface of the unfilled sample, too (Fig.

4 a.2), however the fine structure and the dimensions of the cones. Cs, Ag, and Zn behave in a different way when deposited on surfaces of ultrathin (15−20 Å) films of alumina. In the case of Cs/Al2O3, the alkali atoms wet the oxide, forming strong chemisorption bonds. At small coverages of Cs, desorption of the alkali occurred between and K.

As the amount of Cs deposited increased, there was a reduction in the Cs desorption temperature. Potential-dependent reorientation of a water molecule, adsorption of sulfate, and interactions between water and sulfate on a highly ordered Au() electrode surface in sulfuric acid solutions have been investigated in situ as a function of applied potential by means of surface-enhanced infrared absorption spectroscopy.

The spectrum of the water layer at the interface changes in. This CDTS oscillator has recently been employed to demonstrate spatially localized spectroscopy on rough silver films 42 and to study the dynamics of single metallic colloids. Submicron patterning of the spatial arrangement of spherical silver nanoparticles on a substrate is reported.

The patterned samples were obtained by irradiating a thin silver film in the quasipercolated state with short laser pulses. Light reached the sample through a slit on a highly reflecting silicon mask placed parallel to the surface of the sample and was reflected.

The laser irradiation have shown a range of applications from fabricating, melting, and evaporating nanoparticles to changing their shape, structure, size, and size distribution. Laser induced plasma has used for different diagnostic and technological applications as detection, thin film deposition, and elemental identification.

The possible interferences of. On the other hand, it has been reported that silver aggregates with dense hot spots can directly grow on the interface of indium tin oxide (ITO) and reaction solution by a simple laser-induced photochemical reduction [52,53,54,55].

This laser-direct writing method provides a rapid, controllable, and low-cost way to synthesize SERS active materials. Coloration using semicontinuous metal films has been explored recently and has shown far-reaching interest as a result of being inexpensive, environment-friendly, and non-bleaching.

In this paper, we demonstrate the generation of bright colors through laser modification of semicontinuous Ag films. A palette of colors is obtained from blue through green, orange, up. The sheet resistance of the rough silver (10nm Ag) film is RAg-rough ~51 Ω/sq compared to the smooth silver (10nm Ag/2nm Ge) film with R Ag-smooth ~22 Ω/sq.
