## Description

- description: To enhance the Ag coverage on the Cu surface in the galvanic replacement
    (GR) method, a two-step surface treatment was developed using Ar fast atom beam
    (Ar-FAB) bombardment followed by ethanol vapor-assisted vacuum ultraviolet (E-VUV)
    irradiation. Ar-FAB removed the native oxide from Cu, and E-VUV formed a protective
    layer that prevents Cu reoxidation in air and dissolves readily in AgNO3 solution.
    Compared to the traditional GR method with acid etching, X-ray photoelectron spectroscopy
    (XPS) analyses showed an increased spectrum intensity in Ag 3d and a decrease
    in Cu-O and –OH, indicating better coverage of the Ag layer on the Cu surface.
    The Ag layer thickness grew by about 7 nm during immersion from 10 to 300 s, while
    the traditional GR film stopped growing after 60 s. Scanning electron microscopy
    (SEM) revealed minimal growth of large Ag dendrites.
