Аннотация:The study investigates the ion beam mixing of multilayered CeO₂/Pd films for potential applications in electrocatalysis. The research explores the effects of irradiating the films with He⁺, Ne⁺, and Ar⁺ ions at varying fluences, using both MonteCarlo simulations (TRIDYN code) and experimental techniques such as SEM, SIMS, and X-ray diffraction. Theoretical effective diffusion parameter for ballistic mixing was calculated using TRIDYN. Experimental observations showed films recrystallization for light ions and at low fluences. Ar+ irradiation at the highest fluence (5·1016 cm−2 ) completely disrupted the layered structure, creating a porous, highly mixed film with potential catalytic benefits due to its developed surface.
