Crystal planes of silicon
Webplanes. The lowest energy cleavage planes in silicon are the {111} planes. When a silicon single crystal is loaded to fracture, the cracks tend to initiate along a family of favoured crystallographic planes. In the case of plasma flow treatment of Si (100) surface, favoured cleavage planes are Si {111}, as are given in Fig. 2b. WebJan 13, 2024 · Monocrystalline silicon is a typical anisotropic material, i.e., different crystal planes present different mechanical properties, such as elastic modulus, hardness and …

WebCrystal planes are defined as some imaginary planes inside a crystal in which large concentration of atoms are present. Inside the crystal, there exists certain directions along which large concentration of atoms exists. …
Webon the <111> crystal plane has a higher rate because there are a higher number of surface atoms, i.e. reaction sites or chemical bonds, when compared to a <100> plane. Table 4.3 depicts some of the properties of different silicon crystal planes, whereas Table 4.4 and Figure 4.3 compare the oxidation rates obtained from the <100> and <111> planes.
Webplanes. Depending upon the crystal orientation chosen, the (111) planes are generally either at 54.74 to the wafer’s surface (for (100) silicon) or perpendicular to it (for (110) silicon), as illustrated in Fig. 1(b).
