SP.N junction or P.N junction diode semiconductor How to create potential barrier at P.N junction Reverse bias results in negative terminal Po of the battery

 

SP.N junction or P.N junction diode et semiconductor

What is conductor diode?Answer: P.N junction: A P-type semiconductor is a Connection with N-type Semi-conductorIf done, the junction is created. It is called P.N junction.An electronic device that occurs like this is called a P.N junction diodeSemi-conductor diode is called. Junction making time is as follows Things happen or1. A thin depletion layer is formed. 2. A barrier potential is created across the junction. 3. The growth of the depletion layer depends on the junction and On Capacity.

How to create potential barrier at P.N junction Either write with diagram or describe the religion of P.N junction.  Answer: When a P-type and an N-type Semi-Conductor There, some heat is generated when connected together. As a result starts Free electrons and holes are opposite to each other is diffused to the sides. Electrons move from N-side to P-side and holes are diffused from the P-side to the N-side but when the eletron are diffused on the P-side, then positive charge is created on the N-side. The P-side negative charge is created for such hole diffusion is As a result, subsequent diffusion stops. Because of the N-side positive charge prevents the hole from moving from the P-side to the N-side And negative charge electrons from P-side are transferred from N-side to P- A barrier is created thus blocking the movement to the side. of which For charge carrier’s can no longer travel back and forth. It is called junction barrier or potential barrier. In the figure above It was shown. diffusP Depletion region tvd=ov Figure: Potential barrier In this case the potential barrier is up to 0.3 volt (Ge), 0.7 volt (Si). is Between each of the P and N layers on either side of this barrier Has equal positive or negative charge. That is, there is Neutral.

Another direction prevents the flow of electrons, so it is called potential hill says.

What is Biasing? How many types and what are they?
Answer: Biasing: Bias means external pressure. no component A system of applying external forces to it to make it work Biasing says. Biasing is of two types. Namely : (i) Forward bias (ii) Reverse bias. current Forward bias junction bias junction current hill can be increased.

What do you mean by Forward Bias? Answer: Forward bias P.N Junction: Positive of battery (+ve) terminal P side of PN junction and (-ve) terminal PN junction is connected to the N side of that junction called forward bias. In this condition the depletion layer disappears. Junction resistance decreases and between hole and electron Reverse flow begins. fe reverse potential V

 

What do you mean by reverse bias? Answer: Reverse bias PN junction : When the battery is (-ve) p side of terminal PN junction and (+Ve) terminal PN It is reverse biased when connected to the N side of the junction says These Soyam Holes are attracted to the battery (-ve). by the terminal and electrons are attracted to the battery (+ve) by terminal. As a result there is no current flow. Applied Increases the voltage barrier potential. A little leakage here Current flows for the minority charge carrier.

How does forward biasing the 1P-N junction result?

Explain current flows and write. Answer: PN junction is forward biased and current flows can be don P-terminal side of PN junction of battery Connects positive and (-Ve) terminal of battery on N side

forward bias is applied by connecting See with the help of figure below current flows. P side of PN junction in side diagram Positive of battery and negative of battery on N side terminal is connected. This results in free positive charge (hole) of P-terminal.The junction is repelled by the positive terminal of the battery It will move forward. On the other hand, the negative of the battery is N- The negative charge (free electron) of the terminal is repelled will do As a result, the electron will move towards the junction. In this way Opposite charge will be very close to the junction. In such a situation, if the battery voltage is sufficient, the junction is broken from P-terminal to hole N-terminal and N-terminal Free electrons will enter the P-terminal. As a result The potential hill of the junction will decrease and that of the PN-junction current flows through PN junction 4 reverse bias currrent PN junction 4 reverse bias current Explain that does not flow. Depletion regionnAnswer: Reverse bias: Voltage applied to PN junction If the direction is such that the potential hill across the junction is When the current flow is stopped after increasing, it is called reverse bias says Battery negative at P-terminal of P-N_junction

terminal and connect the positive terminal of the battery to the N-terminal Reverse bias is applied to it.
