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...

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.
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.
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.
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.
Silicon is an indirect band gap semiconductor
Silicon is used in the manufacture of computer chips.
I used to work in Silicon Valley. Microprocessors rely on silicon.
Silicon is the substance in sand that is used in making transistors. Silicon is used as the raw material for producing the silicon wafers, which are then processed to create the transistors.
Silicon is commonly used in compounds such as silicon dioxide (silica) which is found in sand, and in silicon carbide used in abrasives and refractories. Silicon is also used in silicones, a group of synthetic polymers with silicon-oxygen backbones that have a wide range of applications from lubricants to sealants.
Silicon based semiconductors are the most commonly used semiconductor material in calculators. Silicon semiconductors are also extensively used in computers.
Silicon and Germanium are the elements used in transistors
LED was not actually invented, but discovered. It was discovered by H.J. Round in the year 1907 through a crystal of silicon carbide.
Silicon is widely used in semiconductors
They are made from silicon
