Crystal growth
Si crystals grow with a so-called rough interface, except the (111) faces, which grow with an atomically smooth interface—a “faceted” interface. Therefore, the shape and position of the solid–liquid interface can be considered to be identical to the melting point isotherm T m (1413 ± 2 °C [16]) if the facet …
