Morphology Controlled Synthesis of the Nanostructured Gold by Electrodeposition Techniques

Abstract

The gold nanostructures find several technological applications in MEMS, optoelectronics, and electronics industries. To enhance the applicability and suitability of the gold nanostructures in these fields, modification of the morphology of the deposited nanostructure is required. In recent years, the electrodeposition method has emerged as a widely known method for the deposition of the nanostructures of different dimensions and morphologies due to its time efficiency, cost-effectiveness, and absence of vacuum technology. In this method, the morphology of the deposited gold nanostructure can also be easily controlled by tuning the electrodeposition process parameters such as electrolyte concentration, electrolyte temperature, current density, deposition time, etc. This chapter gives a detailed overview of the crucial electrodeposition parameters affecting the morphology of the gold nanostructures deposits.
