Hi guys, let's solve question 93.
00:03
Let's talk about the differences between n -type and p -type semiconductors.
00:12
So, first of all, n -type semiconductor.
00:16
It is an extrinsic semiconductor, which is obtained by doping the impurity, pentavalent atom such as antimony, phosphorus, arsenic, etc.
00:30
To the pure germanium or silicon semiconductor.
00:35
On the other hand, in case of p -type semiconductor, which is an extrinsic semiconductor, which is obtained by doping trivalent impurity atoms, such as boron, gallium, indium, etc., to the pure germanium, or silicon semiconductor.
00:55
So for n -type, the impurity is pentavalent, and for p -type, the impurity is trivalent.
01:04
Number two, for n -type, the impurity atoms added provide extra electrons in the structure and are called donor atoms.
01:15
On the other hand, for p -type, the impurity atoms added, create vacancies of electrons in the structure and are called acceptor atoms.
01:28
In case of n -type semiconductors, the electrons are majority charge carriers and holes are minority charge carriers...
