bcz silicon has direct band gap.in intermediatestage its not required any external energy between conduction band and valence band..due to that radiation willbe less..more external energy more more energy radiate...

How is silicon sulfide used?

Silicon sulfide is used as a semiconductor in electronic devices, such as diodes and transistors. It is also used in the production of solar cells and as a component in ceramics and glass manufacturing. Additionally, silicon sulfide is employed in the production of certain types of abrasives.


Form of silicon?

Silicon exists in a crystalline solid form in nature, such as in the form of silicon dioxide (silica) which is found in quartz. It can also be produced synthetically in various forms including polycrystalline silicon used in solar panels, amorphous silicon used in electronics, and as silicon carbide which is a very hard material used in abrasives.


What is the molecular formula for silicon tetrachloride which has a silicon atom and four chlorine atoms and is used in the manufacture of computer chips?

The molecular formula for silicon tetrachloride is SiCl4. It consists of one silicon atom bonded to four chlorine atoms. Silicon tetrachloride is commonly used in the electronics industry for producing silicon-based materials like computer chips.


What are four chemical or substances silicon contains?

Silicon, silicon, silicon and silicon. Silicon is an element; it doesn't "contain" any other chemicals. If you absolutely insist on getting four things in there, you could say protons, neutrons, electrons and gluons, or up quarks, down quarks, gluons and electrons ... but that's stretching the meaning of "substance" a bit.
