Role of substrate on topography features of nickel deposited nanostructures

Role of substrate in the surface diffusion and kinetic roughening of nanocrystallised nickel electrodeposits

“…One knows that electrodeposition mostly belongs to this growth category [6,12]. The model is based on the scaling behaviour of the interface width or local rms surface roughness (s), as already reported elsewhere [5,13,14]. This topography parameter is expected to obey the law…”

“…As shown in Ref. [5], Cu and Au are both polycrystalline films of face-centred cubic (fcc) structure with Au greatly marked by the [111] preferred growth orientation while ITO is amorphous.…”

“…Usually, their influence is reported from the study of the deposition method effects so that only the film morphology can be examined in that case [4]. Ultimately, their chemical nature plays a crucial role in the growth of nano-crystallised films [5] as it directly affects the surface diffusion of the ad-atoms and the film's kinetic roughening process. The control of each one of these two points and the understanding of their link seem the necessary steps to handle for optimising the global feature of this particular type of films for the specific needs of various application fields.…”

Electrochemical Deposition of Gold Nanoparticles on Pencil Graphite by Fast Scan Cyclic Voltammetry

“…Thus, deposits with peculiar shapes are observed as a result of aggregation of particles as was reported by Gao et al 31 A fast scan rate (2000 mV s -1 ) has been used to produce finer grains and nanoscale deposits. 43,44 In the potential range of 0-850 mV, a scan rate of 1000 mV s -1 and for 1000 cycles, AuNPs with an average size of 81 ± 15 nm were formed. By increasing the scan rate to 5000 mV s -1 and consequently decreasing time for deposition, in the same potential range, nanoparticles have been electrodeposited with an average diameter of 57 ± 13 nm.…”

Analysis of the substrate effect on the nucleation and growth mode of electrodeposited cobalt on copper and graphite electrodes

“…However, it is well known that the nature and surface characteristics of the substrate play a very important role on the initial formation of any electrodeposits. This has consequences on their electronic and optical properties [25], and only a few recent studies [25][26][27][28][29][30][31] deal with this aspect of electrochemical growth. Several papers conclude that the film structure and morphology are sensitive to the substrate nature [26][27][28] whereas other authors demonstrate that the surface preparation influences the film texture [29][30][31].…”
