Abstract: | Conclusion The structure of Ag/Bi prepared by the ion beam sputtering technique is studied by using X-ray diffraction. The longer the modulation period, the more the modulation peaks. This is because a deposition layer can “heal” the roughness of the previous layer, and by lengthening the modulation period, the ability of ”healing” may be reinforced. The internal structures in Ag/Bi multilayers whose substrate is cooled by liquid nitrogen are found to consist of nanocrystalline Ag and Bi; however, the internal structure in multilayers cooled by cooling water is composed of polycrystalline sublayers. The deposition temperature has no effect on interfacial roughness. |
