Fig.9. Distribution of voids (a) and morphology of dendrites in the longitudinal section of the sample (b) (Inset in Fig.9b shows the schematic of dendrites in the circle; θ is the angle between the original dendrite and misaligned dendrite; the circles indicate the same regions with the morphology of voids in Fig.9a and dendrites in Fig.9b)
