Why you do not take pure silicon and use extrinsic silicon material?

Extrinsic silicon is just silicon that has been doped. So it has different semiconducting propeties from pure (intrinsic) silicon.
Why anyone needed to introduce the words intrinsic and extrinsic into the subject always baffled me.

Which electrons in the silicon atom take part in chemical reactions with other metals?
the ones that are furthest from the nucleus
Is silicon rare and unusual?
Silicon is very common. It represents about a quarter of the earth's crust. That's a lot of silicon. But it isn't found free in nature, but as a compound, usually oxides like in sand and the silicate minerals. Use the link below for more information.
What is the structure of silicon?
Silicon can be divided into larger chunks like rocks, or something like sand, or it can be powdered. In its pure form, it takes the shape of a diamond cubic crystal. Silicon is arguably the purest substance that technology makes. And we're real big on making large chunks of pure silicon, which we call ingots. Why? One word: semiconductors. We purify silicon and make big cylinders or ingots of the stuff by growing them. Then we slice the (cooled) ingots like salami, only really thin, and we put the resulting discs (called wafers) through a polishing process to flatten and smooth them. We then take the wafers and put them into vacuum chambers (called reactors) to deposit circuit paths and layers on them. Out comes a wafer with dozens of microprocessors on it. (Other circuits are made, as well, but large scale integration takes up the greatest portion of our efforts.) You need pics, and you got links. Check 'em out. Without what you'll be seeing and the infrastructure built around them, the modern world would disappear. We'd be cast back into something like the 50's.
How long does it take organic material to breakdown?
thousand of years
How can you processed and purified silicon?
When referring to silicon oil in the eye, it is extracted by a vitrectomy machine which has a small cannula attached to a vacuum. Basically it is just sucked out and replaced by balanced salt solution which is isotonic to aqueous in the eye.
What is silicon used for in modern technology?
Silicon is the eighth most common element on earth but only rarely found in its pure form. It is mostly used to make microchips for computers. Silicon is a very good semiconductor, so it can take the heat.It has many other uses, to name a few:Solar panelsGlasswareCircuitry
How long does it take for a massive star's core to become iron from silicon?
from silicon to iron, about a day.
How can boiling point be used to find out if a substance is pure?
At Boiling Point all the material evaporates leaving no residue which means it is pure. But if it leaves some residue after evaporating at boiling point then it is not pure. For example : If you take an example of pure water & Saline Water then pure water will evaporate at its boiling point leaving nothing after it. But Saline water evaporates leaves salt behind it.
How long does it take large silicon crystals to form?
millons of years
Why silicon is preferred over other materials in designing ic?
because1) knee voltage of silicon is .7V where as germanium has .3V 2)silicon breakdown take place at around 200 0C and germanium at 90 0C
What 2 dragons make pure dragon on Dragon City and how long does it take?
marror dragon + winddragon =pure legendarydragon + crastaldragon=pure marrordragon + crastal = pure
Can a led work as a photocell?
If you mean a photovoltaic cell, then no. A photovoltaic cell requires a metalloid to function. The metalloid such as silicon can take on two different types: negative silicon or positive silicon which provides for a slight electric potential. Photons emitted from the sun excite electrons on the surface of the silicon and induce a current between the two plates.
The temperature at which a substance changes from a liquid to a solid is the?
This is called the melting point, and the temperature is different for every material. For pure water, it is zero degrees Celsius, or 32 degrees Fahrenheit. Determining the melting point of any material is an important clue to determining what the material is.
How do you make and light turn on with salt and water?
we take water and put it in a cup and connect wires and we have some chemical that we pure it in water,that chemical is sodium.after we pure it we take salt and pure it in water until the light turn on,but it depend on how much salt we pure,then the light will turn on.
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.
Which electrons in the silicon atom take part in chemical reactions with other metals?
the ones that are furthest from the nucleus
What is a useful material or other material that people take from the earth?
