The phase composition, surface morphology and crystalline structure of carbon-containing silicon layers grown on silicon plates of various orientation by vacuum gas phase epitaxy using different operating conditions are considered. The possibility of phase transition from a Si1−x C x solid solution to silicon carbide upon annealing of the structures obtained by low-temperature epitaxy is
Silicon dioxide is not formed of small molecules. It consists of an infinite array of silicons where each silicon is bonded to four separate oxygens (and each oxygen is shared between two silicons). This creates a strong refractory solid (glass and sand are mostly
Inset: thermal expansion mismatch stress: data (gray) compared with literature models (red, dashed) and linear least squares fit (black, solid). Laser monitoring of the substrate curvature during growth (Figure 2) suggested a thermal expansion coefficient mismatch in sample B of 1.13x10 -6 /°C, which resulted in a slight lattice mismatch increase of 0.15% at 1375°C.
