Growth Mechanism of Si Faceted Dendrite

The growth model of faceted dendrites was proposed in 1960 [17,18]. It was well considered about the role of parallel twins on the growth of faceted dendrite. However, no one has obtained the direct evidences to prove the growth model. Recently, Fujiwara et al. succeeded in observing the growth process of faceted dendrite in detail, and a growth model was presented on the basis of experimental evidence [19], Here, the experimental results of direct observations are shown and both the models are explained.
