Аннотация:This paper involves the laser-induced chemical liquid phase deposition of metals (LCLD). Organic alcohols with low molecular weights, such as ethanol and ethylene glycol, were used as the reductants. The addition of KBrO3 demonstrates how inorganic oxidizing additives affect the process of copper laser deposition from aqueous solutions.
Such additives increase the deposition speed, which is an important challenge in the LCLD method. The depositedcopper structures were investigated by scanning electron microscopy, energy-dispersive analysis (EDX), and impedancespectroscopy. The equivalent circuit of copper tracks was constructed using the impedance spectroscopy data. The studies revealed that the structures deposited from the solutions consist of densely agglomerated nanocrystals, which is in contrast to the microcrystalline deposit obtained in the absence of oxidizing additives.
