Question
The difference between an n-type semiconductor and a p-type semiconductor? the terms on the left to the appropriate blanks on the right to complete the sentences. band When silicon is doped with phosphorus, a group SA element with five valence electrons, its conductivity the phosphorus atoms are incorporated into the silicon crystal structure. but each phosphorus atom brings with it one additional electron Because the band is completely full. the additional elections must go into the band These electrons are then mobile and can conduct electric current This type of semiconductor is called semiconductor Silicon can also be doped with a group 3A element such as gallium which has only three valence electrons When gallium is incorporated into the silicon crystal structure it results in electron 'holes" empty molecular in the band. The presence of holes also allows for the movement of electronic in the band can move between holes in this way the holes move in the opposite direction of the electrons. This type of semiconductor is called semiconductor.Explanation / Answer
Difference between n-type and n-type semiconductor
It is an extrinsic semi-conductor which is obtained by doping the impurity atoms of Vth group of the periodic table to the pure Ge and Si semi-conductor.
The impurity atoms added, provide extra electrons in the structure and are called donor atoms.
The electrons are majority carriers and holes are minority carriers.
The electrons density is much greater than the hole density.
The donor energy level is close to the conduction band and for away from the valence band.
P-type Semi-Conductor
It is an extrinsic semi-conductor which is obtained by doping the impurity atoms of III group of the periodic table to the pure Ge and Si semi-conductor.
The impurity atoms added, create vaccines of electrons (i.e. holes) in the structure and are called acceptor atoms.
The holes are majority carriers and electrons are minority carriers.
The holes density is much greater than the electrons density.
The acceptor energy level is close to the Valence band and for away from the Conduction band.
Fill in the blanks:
1) Conduction band
2) Conductivity increases
3) Valance band is full
4) Conduction band
5) n - type
6) Valance band
7) Conduction band
8) p - type
