The texture and colour changes allowed the characterization of the different phases and transitions in which they are involved on cooling as well as on heating processes. The type of crystallization front and its velocity were also followed by microscopic observation.

Web1 de nov. de 2024 Β· Fig. 1 is the molecular dynamics model of silicon crystal growth from the melt, which consists of the crystal nucleus in the center segment and the silicon melt at the left and right segments. The melt segments are cut from a pre-melting system at high temperature. The interface is exactly the grown plane. Weblatter reason, melt growth is commercially the most important method of crystal growth. The preferential role of the electrochemical process responsible for the change in composition of the crystals when they grow in melt in an applied field has been studied (Balasanyan et al1990). The growth from melt can further be
