In this work, the features of In particle electrodeposition from aqueous solutions were shown. The dependence of the morphology and geometric characteristics of the In particles on the parameters of the electrodeposition process were obtained. For each case, a scanning electron microscopy image was presented, which was used to analyze the morphology and estimate the average size of indium particles. A study was carried out to determine the type of nucleation of In particles during deposition in the potentiostatic mode depending on the applied potential and the concentration of In in the solution. It has been established that at potentials of − 1 V and − 1.1 V, as well as an InCl3 concentration of 0.01 M and 0.02 M in the solution, the nucleation of In occurs by the instantaneous type. When studying the process of In deposition in the galvanostatic mode, it was shown that with an increase in the InCl3 concentration in solution from 0.002 to 0.02 M, the average particle size increased almost linearly, while their number per unit area decreased exponentially. The unique properties of particles due to surface and quantum-dimensional effects depend directly on their size. In addition, if the particles are used as seed particles in the growth process of one-dimensional semiconductor structures, the size of indium particles affects the diameter of one-dimensional structures. Therefore, it is important to obtain indium particles of certain sizes. [ABSTRACT FROM AUTHOR]
