Figure 6From: The surface condition effect of Cu2O flower/grass-like nanoarchitectures grown on Cu foil and Cu filmEx situ θ /2 θ diffractograms measured for X-ray stress analysis. (a) Unpolished Cu foil, (b) polished Cu foil (400 grit), and (c) Cu film specimens before heating. The legend reports the corresponding ψ angles (i.e., inclination of the specimen).Back to article page
