Why silicon dioxide used in MOSFET instead of any other material which have high k-dielectric?
Because the gate terminal should highly resistive..
silicon dioxide has high resistance and hence gate current is very very low...
What else can I help you with?
Is silica dioxide quartz an organic molecule?
No. It is neither organic nor a molecule. Silicon dioxide consists only of silicon and oxygen. By definition, an organic compound must contain carbon. Second, silicon dioxide forms a covalent network rather than molecules.
What is the name of the chemical formula for quartz?
Silicon dioxide, or SiO2
Of these 4 copper wood silicon aluminum which material would have the highest resistance to the flow of electric current?
silicon
Which volcanic rock has the highest level of silicon dioxide rhyolite or basalt?
Rhyolite.
Why silicon is mostly used as a semiconductor material in electronic industry as compared to germanium and other semiconductor material?
Mostly because of their cost but also because silicon transistor have faster switching properties and are far more resistant to damage by heat. Silicon transistor also have a much wider operating band.
Is silicon dioxide a homogeneous or heterogeneous?
Silicon dioxide is a homogeneous mixture, as it is a compound composed of silicon and oxygen atoms uniformly distributed throughout the material.
What are the differences between Silicon Dioxide and Diamond?
Silicon dioxide is a compound composed of silicon and oxygen atoms, while diamond is a pure form of carbon arranged in a crystalline structure. Diamond is the hardest naturally occurring material, while silicon dioxide is not as hard. Additionally, diamond is a valuable gemstone, whereas silicon dioxide is commonly found in materials like sand and quartz.
Can silicon burn in the air?
Silicon does not burn in the air because it is a non-combustible material. It can react with oxygen at very high temperatures to form silicon dioxide, but this is not a combustion reaction.
Why poly-silicon is used as gate material instead of metal?
Polysilicon is used as a gate material in MOSFETs because it is a good conductor, it is compatible with silicon technology, it forms a good interface with silicon dioxide, and it has a thermal expansion coefficient that matches that of silicon. Additionally, polysilicon allows for self-aligned gate formation, better gate control, and lower manufacturing costs compared to using metal gates.
The structure of silicon dioxide consists?
Silicon dioxide has a tetrahedral structure where each silicon atom is covalently bonded to four oxygen atoms. This forms a three-dimensional network of SiO2 molecules, creating a hard and brittle material. Silicon dioxide is commonly found in nature as quartz or as a major component of glass.
Which mineral is composed of silicon dioxide?
Quartz is composed of silicon dioxide.
Is silicon dioxide reactive?
silicon dioxide is reactive when eating egg
Is silicon dioxide an insulator?
Yes, silicon dioxide is an insulator. It is a material commonly used in the production of insulating layers in electronic devices due to its high resistivity and ability to block the flow of electric current.
What does the structure of silicon dioxide consist of?
The structure of silicon dioxide consists of silicon atoms bonded to four oxygen atoms in a tetrahedral arrangement. These tetrahedra link together to form a three-dimensional network structure, resulting in a rigid and crystalline material. Silicon dioxide can exist in different forms such as quartz, amorphous silica, and glass, depending on the arrangement of its atomic structure.
What are common compounds found in silicon?
Common compounds found in silicon include silicon dioxide (SiO2), silicon carbide (SiC), and silicon tetrachloride (SiCl4). Silicon dioxide, in the form of quartz or sand, is the most abundant compound and is used in making glass and ceramics. Silicon carbide is a hard material used in abrasive products and cutting tools, while silicon tetrachloride is a precursor in the production of silicon metal.
What is the balance of silicon reacts with carbon dioxide form silicon carbide and silicon dioxide?
The balanced chemical equation for the reaction between silicon and carbon dioxide to form silicon carbide and silicon dioxide is: 3Si + 3CO2 -> SiC + 2SiO2
Is silicon dioxide a atom?
Silicon dioxide is a compound, not an atom. It is composed of one silicon atom and two oxygen atoms bonded together. Each of the atoms in silicon dioxide retains its individual identity within the compound.
