WebThe crystallization temperature of SiC thin films sputtered from an SiC target is about 500°C, below which the films are amorphous. However, the stable amorphous phase is obtained in SiC thin films reactively sputtered from a Si target in a C 2 H 2 or CH 4 gas. [288] Typical sputtering conditions for the deposition of amorphous SiC films are shown in Table 5.56. Crystallization is the process by which solid forms, where the atoms or molecules are highly organized into a structure known as a crystal. Some ways by which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas. Attributes of the resulting crystal depend … See more The crystallization process consists of two major events, nucleation and crystal growth which are driven by thermodynamic properties as well as chemical properties. Nucleation is the step where the solute molecules or atoms … See more Crystal formation can be divided into two types, where the first type of crystals are composed of a cation and anion, also known as a salt, such as sodium acetate. The second type of … See more As mentioned above, a crystal is formed following a well-defined pattern, or structure, dictated by forces acting at the molecular level.
