Silicon used in making chips must be very pure because if it is not, the chip will not work.
Silicon dioxide is a substance (chemical compound) consisting of one silicon atom and two oxygen atoms.
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.
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.
by melting the pure alumnuim at 750c then add the pure powder silicon (12.6 wt%) to it with contineous stirring.
silicon tetrachloride is used1-To obtained pure silicon which is used as semiconductor2-In the formation of photo voltaic cell.Answered by;Asim MukhtarU.E.T. LAHORE
Pure silicon is a semiconductor.
silicon is a pure substance because it is an element and as we know an element is a pure substance
In pure form Silicon is a solid.
Silicon dioxide is a substance (chemical compound) consisting of one silicon atom and two oxygen atoms.
Pure silicon is gray in color and has a metallic luster
silicon and germanium
Yes but if it is pure silicon then the paint wont stick to it.
Because only about one from million atoms has a free electron
Very. Doping determines the conductivity, pure silicon is a good insulator.
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.
Intrinsic means no dopants. (a term used in semiconductors) So it means the same as pure.
