P-N junction and Knee Voltage
P-N Junction:
A P-N junction is formed by bringing a P-type and an N-type semiconductor material in close contact with each other. The semiconductor material is typically silicon or germanium. In a P-type semiconductor, the majority carriers are holes, while in an N-type semiconductor, the majority carriers are electrons.
Knee Voltage:
The knee voltage is the voltage at which the diode starts conducting. It is also known as the cut-in voltage or the threshold voltage. The knee voltage is the voltage required to overcome the potential barrier at the P-N junction and cause the flow of current through the diode. The knee voltage is typically around 0.6 to 0.7 volts for silicon diodes and around 0.2 to 0.3 volts for germanium diodes.
Other Voltage Terms:
There are several other voltage terms associated with a P-N junction diode:
- Cut off voltage: The cut off voltage is the voltage at which the diode stops conducting. It is also called the reverse breakdown voltage.
- Saturation voltage: The saturation voltage is the voltage at which the diode is fully conducting and no further increase in current can be achieved by increasing the voltage.
- Breakdown voltage: The breakdown voltage is the voltage at which the diode breaks down and starts conducting in the reverse direction. It is also called the reverse breakdown voltage.
Conclusion:
In summary, the knee voltage is the voltage at which the diode starts conducting, and it is caused by the potential barrier at the P-N junction. The other voltage terms associated with a P-N junction diode include the cut off voltage, saturation voltage, and breakdown voltage.
