Thickness modulation effect of CeO2 layer for YBCO films grown by pulsed laser depositionXiang Wu,Lin-Fei Liu,Yan-Jie Yao,Meng-Lin Wang,Bin-Bin Wang,Yi-Jie LiDepartment of Physics and Astronomy... structure and morphology of CeO2 films with thickness ranging from 21 to 563 nm were systematically characterized by means of X-ray diffraction(XRD), atomic force microscope(AFM) and reflection high......
: Polyimide-supported and silicon-supported Cu-Cr nanostructured metallic multilayers with constant modulation ratio (η) and constant modulation period (λ) were respectively synthesized by means... effect at a critical modulation period λc (≈25 nm) or a critical modulation ratio ηc ( ≈1). Key words: nanostructured metallic multilayers; strength; hardness; modulation period; modulation ratio 由两种或......
modulation period on the modulation ratio was investigated by uniaxial tensile testing. The heterogeneity restriction effect of the multilayers affecting the fracture behavior was further studied through quantitative focused ion beam(FIB) and scanning electron microscope (SEM) cross-section characterization technique. The results show that the ductility of multilayers decreases with increasing modulation......
