Q. Write down five differences between N-type and P-type semiconductors
An N-type semiconductor is a mixed semiconductor material with impurities that are utilized in electronics. n-type semiconductors are made from pentavalent impurity atoms such as phosphorus, arsenic, antimony, bismuth, or another chemical element.
The impurity in a p-type semiconductor is trivalent impurities from the III group elements. Aluminum, Indium, and Gallium are all trivalent impurities that are added to the intrinsic semiconductor. In a p-type semiconductor, holes make up the majority of the carriers.

P-TYPE SEMICONDUCTOR |
|
Nitrogen, Phosphorus, Arsenic, Antimony, and Bismuth are doped to generate an N-type semiconductor |
The doping of III group elements such as Boron, Aluminum, and Thallium results in the formation of a P-type semiconductor |
|
Pentavalent impurities are added are also known as p type semiconductors |
Trivalent semiconductors are another name for these |
|
The term “N-type semiconductor” refers to a semiconductor that requires an excess of one electron |
P-type semiconductors are positive type semiconductors, which implies they require a one-electron shortage |
|
Electrons carry the majority of charge in N-type semiconductors, while holes carry the minority |
The bulk of charge carriers in a P-type semiconductor is holes, while the minority charge carriers are electrons, which carry the majority of charge in N-type semiconductors, while holes carry the minority |
|
The number of holes in an N-type semiconductor is fewer than the number of free electrons |
A hole signifies that an electron is missing, the number of holes in this system is greater than the number of electrons |
