Silicon
Electron Mobility
Depend on electron and hole concentrations in which the carriers are transport through the crystal [6]
-
-
Influence by presence of crystalline defects that are responsible for scattering of electrons in metal [6]
-
Applications
i)Used to make dynamo and transformer plates, engine blocks, cylinder heads and machine tools and to deoxidise steel.[3]
-
-
Silica
-
Silica is the one stable oxide of silicon, and has the empirical formula SiO2. [1]
-
Semiconductor
Silicon is perfect for making this lattice structure because its four valence electrons allow it too perfectly bond to four of its silicon neighbors. [1]
-
Doping refers to a process by which impurities are introduced into ultra pure silicon, thereby changing its electrical properties and turning it into a semiconductor. [1]
-
Properties
-
Chemical
-
Combine with oxygen, nitrogen , phosphorus , sulfur at high Temperature (in molten state)[4]
-
Appearance
Pure silicon is a hard, dark gray solid with a metallic lustre and with a octahedral crystalline structure the same as that of the diamond form of carbon[1]
In compounds, silicon dioxide occurs both in crystalline minerals (e.g., quartz, cristobalite, tridymite) and amorphous [2]
Silicates
-
Primary ingredient in building components such as bricks, cement, ceramics, and tiles.[1]
Crystal Structure
Face Centered Cubic (FCC , a : 0.543nm)
