“…Similar N crit values were found in the systems highly oriented pyro-graphite (HOPG)(0001)/Pb 2ϩ and Ag(hkl)/Pb 2ϩ for the N RT zF d J d crit ϭ ln 3D Pb phase formation in comparable OPD ranges. 1,29,30,40 Obviously the size of the critical clusters in 3D Pb phase formation processes is mainly determined by the Pb-Pb interaction. Furthermore, the low number of atoms in the critical cluster indicates that the nucleation process has to be described by an atomistic model instead of macroscopic theories.…”

The local formation and dissolution of low-dimensional phases and small clusters on foreign substrates plays an important role in modern nanotechnology. This paper deals with the current state of nanostructuring of semiconductor surfaces by localized electrochemical metal deposition using in situ scanning tunneling microscopy as a nano-tool. New experimental results of delocalized and localized electrochemical deposition and dissolution of Pb on n-type Si(111) single-crystal surfaces are presented. The influence of surface inhomogeneities on the local metal deposition process is considered.

“…Some studies on nucleation and growth at the initial stages of metal electrodeposition and nanoparticle formation have used Scanning Probe Microscopy (SPM) techniques, as STM and ECSTM [30,52,[62][63][64][65] or AFM [39,48,[66][67]. These nanometric techniques yield information on an atomic scale and provide a view of the electrodeposition process in a nanometric scale.…”

Electrochemical nucleation: comparison test of classical and atomistic nucleation models

Classical and atomistic nucleation models have been tested in several aqueous systems dealing with electrocrystallization. A lot of reported experimental nucleation data have been used, and in a wide range of overpotentials. The critical nucleus size has been calculated in those cases not reported in the original work, and the results obtained with the classical and atomistic models have been tabulated, compared and discussed. Small values for the critical nucleus size occur in most of the systems.

“…The most important technologies of significance for the practical application of lead are the production of high purity active material for acid batteries [1], for semiconductors [2,3], and in the fabrication of electrochromic devices [4]. Lead in the form of powder has found multiple applications in many industries including oil and gas exploration, radiological medical protective clothing, as an industrial X-ray shield, golf club manufacture, and anti-friction products (http://www.nuclead.com/ leadpowderapps.html).…”

Electrodeposition of lead from nitrate electrolyte in constant regimes of electrolysis was analyzed and the obtained powder lead deposits were examined by scanning electron microscopy. Polarization curve for lead electrodeposition consisted of two parts separated by an inflection point. The first part of the polarization curve was characterized by a linear dependence of the current density on overpotential. The linear part of the polarization curve corresponded to ohmic-controlled electrodeposition and single lead crystals were formed in this range of overpotentials. A rapid increase in the current density with increasing overpotential was observed after the inflection point (the second part of the polarization curve). Two-dimensional dendrites were the dominant morphological forms obtained at overpotentials and current densities belonging to the second part of the polarization curve, indicating that the rapid increase of the current density with increasing overpotential corresponded to activation controlled electrodeposition at the tips of the formed dendrites. Comparing the morphologies of the obtained lead deposits with those belonging to the same group of metals (metals characterized by a high exchange current density), such as silver, cadmium, and tin, a strong dependence between the nucleation type and the shape of dendrites for the metals belonging to the same group was established.
