Research
My work during my visit in NIMS (Japan) explores how combining Ar-FAB oxide removal with E-VUV irradiation enables a new surface modification pathway in galvanic replacement.
Lowering interfacial free energy reduces the nucleation barrier (ΔG*) and stabilizes the coupled Cu dissolution–Ag⁺ reduction reactions. This leads to continuous, uniform Ag growth while suppressing dendritic structures - offering a new physics perspective for controlled thin-film deposition.
