What is "silicon"?
Silicon (Silicon) is a chemical element, pronounced [ˈsɪlɪkən], code-named Si, atomic number 14, relative atomic mass 28.09, and belongs to inorganic substances. It is the most common element in the world, accounting for 27.7% of all elements in the earth's crust, ranking fourth. It often has a high content in volcanic lava and crustal fissures, and the content is also very low, but it mostly occurs in turbid soil deposits such as peat and sand ash in different regions.
The shape of the silicon atom in the crystal structure is tetrahedral, which looks like a complete sphere, and this shape can be changed by a strong electric field. Under natural conditions, silicon often has a large number of oxygen atom components, forming silicates. At higher temperatures, silicon and oxygen can be combined to form calcium glass.
Silicon relies on raw material resources and survives more than 20 kinds. Of these types, the most commonly used in the semiconductor circuit and electronic component manufacturing industry is pure silicon, which is rearranged as a p-type or n-type semiconductor. N-type semiconductors are composed of 5% type chlorine atoms and 95% silicon atoms, while p-type semiconductors are composed of 5% phosphorus atoms.
In addition, silicon can also be diffused into various crystal shapes through high-temperature polysilicon (poly-silicon), which is used to make electronic devices such as optoelectronic devices and components. A semiconductor can be simply said to be a combination of conduction electrons and non-conduction electrons, and its raw materials are determined by the electron transfer behavior between atoms. In addition to silicon, silica gel is one of the most important similar raw materials. It is composed of silicon and silicon oxide (silicon dioxide), and is mainly used for repairing and repairing open circuit circuits.
