Becoz the n-type semi-conductor is formed by the elements which are in stable state and has one more free electron with them.........
Mostly n-type semi-conductor's are formed with the elements of the 1st and 3rd group elements which are rich in free electron's..........

In n-type semiconductors, electrons are the majority carriers because dopant atoms, such as phosphorus or arsenic, introduce extra electrons into the crystal lattice. These extra electrons are free to move and contribute to the conductivity of the material, making electrons the dominant charge carriers in n-type semiconductors.

What are the majority and minority current carriers in an N-type and a P-type semiconductor?
In an N-type semiconductor, majority current carriers are electrons, while minority current carriers are holes. In a P-type semiconductor, majority current carriers are holes, while minority current carriers are electrons.
What is the difference between p-type and n-type semiconductor?
A p-type semiconductor has an excess of positively charged "holes" in its crystal lattice due to doping with acceptor atoms, while an n-type semiconductor has an excess of negatively charged electrons due to doping with donor atoms. This fundamental difference in charge carriers leads to variations in conductivity and behavior of the two types of semiconductors.
What is an n-type semiconductor?
An n-type semiconductor is a type of material that has been doped with impurities to increase the number of free electrons, giving it a negative charge. This excess of electrons allows the material to conduct electricity more easily. N-type semiconductors are commonly used in electronic devices due to their ability to carry current.
What are the examples of p-type semiconductors?
Examples of p-type semiconductors include materials like boron-doped silicon, gallium arsenide, and aluminum gallium arsenide. These materials have a deficiency of electrons, leading to "holes" in the crystal lattice that behave as positive charges.
IS indium a p type semiconductor?
No, indium is not a p-type semiconductor on its own. Indium is typically used as a dopant in semiconductors to tune their electrical properties, such as increasing the conductivity or modifying the bandgap.
What is the majority carrier in an n type semiconductor?
p-type majority carriers are holes n-type majority carriers are electrons
What is majority carrier in p type semiconductor?
electron
What are the majority and minority current carriers in an N-type and a P-type semiconductor?
In an N-type semiconductor, majority current carriers are electrons, while minority current carriers are holes. In a P-type semiconductor, majority current carriers are holes, while minority current carriers are electrons.
Why p type semiconductor has majority charge carrier as hole?
The majority carrier in p-type semiconductor is the hole. Electron carriers in p-type semiconductor are minority carriers. Minority carriers in any semiconductor are produced mainly by heat. Only at absolute zero temperature would there be no minority carriers.
What is the difference between the minority charge carriers and majority charge carriers in diodes?
Majority charge carriers in the N-type side of a semiconductor material are electrons, because N-type semiconductor is doped with a material with 5 valence electrons. Semiconductor materials have 4 valence electrons and hold tightly to 8, so there is a "loose" electron for every atom of dopant. Therefore most of the charge carriers available are electrons. IE, electrons are the majority charge carriers. Minority charge carriers in N-type semiconductor are holes. Only a few holes (lack of an electron) are created by thermal effects, hence holes are the minority carriers in N-type material. The situation is reversed in P-type semiconductor. A material having only 3 valence electrons is doped into the semiconductor. The semiconductor atoms have 4 valence electrons try to hold tightly to 8, so there is a virtual hole created by a "missing" electron in the valence orbit. This acts as if it were a positive charge carrier. Most of the charge carriers are these holes, therefore in P-type semiconductor holes are the majority charge carrier. Again, reverse situation to minority charge carriers. Some electrons are loosened by thermal effects, they are the minority charge carriers in P-type semiconductor.
Diffrentiate n-type and p-type?
When pentavalent impurity is added to pure semiconductor, it is known as N-Type semiconductor. In N-type semiconductor electrons are majority carriers where as holes are minority carriers. impurities such as Arsenic, antimony are added. When trivalent impurity is added to pure semiconductor, it is know as P-type semiconductor. In P-type semiconductor holes are majority carriers whereas electrons are minority carriers. Impurities such as indium, galium are added.
What is the the term for a semiconductor that is missing electrons?
p-type semiconductor A semiconductor that is missing electrons is called an electron hole.
What is the term for a semiconductor that is missing electrons?
p-type semiconductor A semiconductor that is missing electrons is called an electron hole.
What is term for a semiconductor that contains extra electrons?
N-type semiconductor contains extra electrons.
What is minority charge carrier?
In semiconductor devices there are two types of charge carriers: electrons and holes. In N-type doped semiconductor the majority charge carriers are electrons and the minority charge carriers are holes. In P-type doped semiconductor the majority charge carriers are holes and the minority charge carriers are electrons.Some kinds of semiconductor devices operate using minority charge carriers in part(s) of their structure. The common bipolar junction transistor is one of these, they are sensitive to a phenomenon called thermal runaway because additional minority carriers are produced as temperature increases. (field effect transistors however operate using only majority carriers and are thus not sensitive to thermal runaway)
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.
What is the term for a semiconductor that is missing electronic?
p-type semiconductor A semiconductor that is missing electrons is called an electron hole.
