“…Previously, the present author has studied the oscillatory electrodeposition of various metals and alloys, with a focus placed on the self-organized formation of ordered structures [92,[95][96][97]100,105,106,127,128,130]. Although the oscillatory electrodeposition studied included NDRs of quite different types, it has been revealed (by the present author) that the layered structures are formed spontaneously in synchronization with the oscillation, independent of the type of NDR.…”

Solid surfaces with ordered nanostructures, such as layers, dots, holes, and grooves (or ridges), have provided unique microelectronic, optical, magnetic, and micromechanical properties, as summarized in a recent review [1]. Focused photon-, electron-, ion-, and molecular-beam lithography (top-down method) have been widely used for creating desired nanostructures at the surface. However, these techniques are now facing serious problems, such as difficulties in mass production and cost increases due to the use of expensive, specialized apparatus. In the hope of overcoming those problems associated with the conventional techniques, a self-organization method (bottom-up method) has recently attracted much attention.In general, self-organization methods in chemistry can be categorized into two different types. One type is self-organization under thermodynamically equilibrium conditions, in which the ordered structures are formed on the basis of specific properties of intermolecular forces. Self-assembled structures, such as lipidbilayers, close-packed layers of nanospheres, and monolayers of thiol molecules on gold surfaces, are the representative examples. Many studies have been performed on this type of self-organization, as summarized in reviews [2][3][4][5][6][7][8][9][10]. At present, the main issues to be tackled for these methods are to improve their regularity and to be able to place nanostructures of desired size at desired locations. In the other type of self-organization, the ordered structures are formed under thermodynamically nonequilibrium conditions. A wide variety of dynamic spatiotemporal orders, such as oscillations and spatiotemporal patterns, appear in a self-organization manner [10][11][12][13].The spatiotemporal patterns in the dynamic self-organization phenomena have some unique and attractive properties for producing materials of ordered structures: j267 Nanostructured Materials in Electrochemistry. Edited by Ali Eftekhari . The patterns appear spontaneously, without any external control. . The observed patterns have a long-range order. . Various ordered patterns are obtained simply by changing experimental parameters.In fact, several studies have been performed on the application of dynamic selforganization for the formation of ordered structures. For example, the self-organized formation of 2-dimensional (2D) ordered patterns on nano-and micro-meter scales have been achieved by use of , etching [15,16], and dewetting processes [17,18]. These ordered 2D patterns on solid surfaces have already been used in practical applications as templates for constructing three-dimensional (3D) structures and substrates for the incubation of biological cells. 268j 6 Self-Organized Formation of Layered Nanostructures by Oscillatory Electrodeposition 274j 6 Self-Organized Formation of Layered Nanostructures by Oscillatory Electrodeposition

Potential oscillation was observed during the template-free galvanostatic deposition in the 58/42 mol% AlCl 3 /trimethylamine hydrochloride ionic liquid, and resulted in the formation of unique periodic (accordion-like) aluminum wires with variable periodicity and diameter controlled by the deposition current density. Factors leading to this phenomenon are postulated. © The Author(s) 2015. Published by ECS.

Published May 5, 2015 Potential oscillation during galvanostatic electrodeposition and current oscillation during potentiostatic electrodeposition are of interesting because these phenomena often associated with the production of deposits having interesting spatial patterns in the microor nano-scale. Many examples acquired in aqueous systems have been reported including tine metal latticework consist of cuboids connected by needles, 1,2 stacked alternated layers of metals or alloys, [3][4][5] dendrites, 6,7 and metal wires with periodically changed diameters. 8-10Often, the oscillation is associated with negative differential resistance (NDR), 11 and has been attributed to the reactions such as formation of passivation layer, autocatalytic growth, adsorption of additives (levelers and accelerants), and restricted mass transport of ions.Ionic liquids (ILs) have attracted numerous interests in electrochemistry and electrodeposition 12,13 especially for the deposition of materials such as Al 14 that are difficult to obtain from aqueous baths. Materials with various morphologies, specifically, metals/alloys wires, [15][16][17][18][19][20][21] have been electrodeposited from ILs with and without the need of template. Nevertheless, reports on electrochemical oscillation in IL are very limited. 22,23 Schaltin et al. 23 discussed the current oscillation during potentiostatic electrolysis of EMIC IL containing both Cu(II)/Cu(I), and found the presence of both Cu(II) and Cu(I) is essential for the oscillation to occur. Here, we report the potential oscillation during the template-free galvanostatic deposition of Al from a quiescent 58/42 mol% AlCl 3 /trimethylamine hydrochloride (AlCl 3 /TMHC) IL, which leads to the formation of Al wires with diameters change periodically. According to the literature, 24 The complex ion chemistry in the AlCl 3 /TMHC is similar to that for the AlCl 3 /1-ethyl-3-methylimidazolium chloride (AlCl 3 /EMIC) ILs, but the former ILs exhibit higher melting points and higher viscosities than the later ILs do. To our knowledge, galvanostatic de...
