N-Type Semiconductors and Donor Energy Level
N-Type Semiconductors:
N-Type semiconductors are a type of extrinsic semiconductor that is doped with impurities such as phosphorus, arsenic, or antimony. These impurities are known as donor impurities because they donate an extra electron to the semiconductor crystal.
Donor Energy Level:
When a donor impurity is added to a semiconductor crystal, an extra energy level is introduced just below the conduction band. This extra energy level is called the donor energy level.
Explanation:
The donor energy level is important because it provides an additional source of electrons that can participate in conduction. The electrons in the donor energy level are loosely bound to the impurity atom and can be easily excited into the conduction band, where they can move freely through the crystal.
In an N-Type semiconductor, the concentration of donor impurities is typically much higher than the concentration of other impurities, such as acceptor impurities. This means that the concentration of electrons in the conduction band is also higher, making N-Type semiconductors good conductors of electricity.
Conclusion:
In summary, N-Type semiconductors are doped with donor impurities, which introduce an extra energy level called the donor energy level. This energy level provides an additional source of electrons that can participate in conduction, making N-Type semiconductors good conductors of electricity.
