Distinguish between P-type and N-type semiconductor.
N- type Semiconductor
|
P- type Semiconductor
|
When small amount of pentavalent impurity is added to a pure semiconductor is called N-type semiconductor
|
When small amount of trivalent impurity is added to a pure semiconductor is called P-type semiconductor
|
Impurity is used for doping is arsenic, antimony, phosphorus
|
Impurity is used for doping is gallium, indium, boron, aluminium
|
It is called donor impurity
|
It is called acceptor impurity
|
There are excess of electrons
|
There are shortage of electrons
|
The electrons are majority carriers
|
The holes are majority carriers
