What is amorphous semiconductor?
it is like p type semiconductor because when adding impurity its conductivity decreases
What is doping in conductor?
The process of adding suitable impurities in the intrinsic semiconductor is called doping. The impurity added to the intrinsic semiconductor to increase its conductivity is called dopant. There are some methods of doping in case of a conductor.impurity atoms can be added to the intrinsic semiconductor in different ways discussed below:A very small quantity of impurity atoms is made by diffusing into the high purity molten material such as germanium when the crystal is grown out of melt.Impurity atoms can also be added into the intrinsic semiconductor by heating it in the environment having impurity atoms.Impurity atoms can also be added into the intrinsic semiconductor by bombarding it with the impurity atoms.
What type of semiconductor is produced by using trivalent impurity?
P
What do you call of a semiconductor decreases while doping increases?
Impurity
What happens when you add a small amount of impurity to silicon it turns into a?
semiconductor.
Which serve as a donor impurity in silicon?
Which will serve as a donor impurity in silicon is boron or germanium or antimony or indium
What is the amount of impurities in pure semiconductor to make it extrinsic semiconductor?
the impurity add here is 1 atom of per million atoms of semiconductor.......
What is the nature of bonds in N type and P type semi conductors?
The bonds in a N type or a P type semiconductor depends upon the impurity added into it. For example a trivalent impurity is added then three bonds will be formed by each atom and it becomes a P-type semiconductor whereas if a pentavalent impurity is added then five bonds will be formed by each and every atom and it becomes a N-type semiconductor.
What effect do added impurities have on semiconductor conductivity?
It is called as DOPING. Doping is the process in which you add an impurity to a pure semiconductor to increase its conductivity. While doping is done, crystal structure of semiconductor is not disturbed.
Is coffee an impurity?
if dissolved in water, it can be called an impurity.
What extrinsic semiconductor is?
Those semiconductors in which some impurity atoms are embedded are known as extrinsic semiconductors.
How the n type and p type semiconductor is joint without adding any impurity?
doping
