What happens when heat is added to silicon?
An intrinsic (pure) silicon crystal at room temperature has sufcient heat (thermal)energy for some valence electrons to jump the gap from the valence band into theconduction band, becoming free electrons.
Is silicon dioxide a mixture or pure substance?
Silicon dioxide is a substance (chemical compound) consisting of one silicon atom and two oxygen atoms.
Why does silicon have to be very pure?
Silicon used in making chips must be very pure because if it is not, the chip will not work.
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.
Explain why arsenic-doped silicon conducts electric current better than pure silicon?
Pure silicon is intrinsic. It has a high resitivity which means it is a poor conductor of electricity in this state. The dopant that is introduced during the doping process can be arsenic, boron or phosphorous. These are the traditional choices to dope the intrinsically pure silicon. After the pure silicon becomes doped its electrical properties change. The main change is it has a lower resistivity and will conduct electricity. This is why silicon is called a semiconductor.

What happens to the amount of kinetic energy when heat is added to a pure phase of matter?
The kinetic energy increases as you add more heat.
Is pure silicon an insulator?
Pure silicon is a semiconductor.
Why silicon is a pure substance?
silicon is a pure substance because it is an element and as we know an element is a pure substance
Is pure silicon a semiconductor?
A silicon chip is a structure created by people using machines. The structure consists of a base, made of silicon with a small amount of other elements added, so this part is a mixture. The chip also has wiring and transistors printed on it, thus making the entire chip a structure rather than a mixture or pure substance.
What is the form of silicon?
In pure form Silicon is a solid.
Is silicon dioxide a mixture or pure substance?
Silicon dioxide is a substance (chemical compound) consisting of one silicon atom and two oxygen atoms.
Why does silicon have to be very pure?
Silicon used in making chips must be very pure because if it is not, the chip will not work.
What is the colour of silicon?
Pure silicon is gray in color and has a metallic luster
What are pure semiconductors?
silicon and germanium
Can clear silicon be painted?
Yes but if it is pure silicon then the paint wont stick to it.
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.
