## What is p/n junction explain forward bias?

A P-N junction diode is said to be forward biased when the positive terminal of a cell or battery is connected to the p-side of the junction and the negative terminal to the n side. When diode is forward-biased the depletion region narrows and consequently, the potential barrier is lowered.

What is energy band diagram of pn junction diode?

The Fermi level lies close to the conduction band in n-type material and it is close to valence band in p-type material. When a p-n diode is made with p-type and n-type materials, then flow of free charge carriers takes place at the junction.

What is energy level diagram in semiconductor?

In solid-state physics of semiconductors, a band diagram is a diagram plotting various key electron energy levels (Fermi level and nearby energy band edges) as a function of some spatial dimension, which is often denoted x.

### When two semiconductors are brought in contact with each other and the Fermi energy of p-type region and n-type region equalize such that EFP EFN it results in?

When two semiconductor of p-type and n- type are brought in contact, they form p-n junction which act like a rectifier.

How does a pn junction behave under forward and reverse biased condition?

Forward biasing indicates the application of a voltage across a diode that enables current to flow easily, while reverse biasing means putting a voltage across a diode in the opposite direction.

What do you mean by forward bias and reverse bias with suitable diagram?

Forward biasing means putting a voltage across a diode that allows current to flow easily, while reverse biasing means putting a voltage across a diode in the opposite direction. The voltage with reverse biasing doesn’t cause any appreciable current to flow. This is useful for changing AC current to DC current.

## What is meant by forward bias?

Biasing is such an arrangement made in the PN junction device so that the device allows the flow of larger current in one direction. The device is said to be forward biased if the anode is connected to the positive end and cathode is connected to the negative end of the battery.

What is forward bias condition?

Overview. Forward bias occurs when a voltage is applied across the solar cell such that the electric field formed by the P-N junction is decreased. It eases carrier diffusion across the depletion region, and leads to increased diffusion current.

How is P type semiconductor formed?

The p−type semiconductor is formed when the Trivalent impurity is added to the pure semiconductor.

### What is the type of semiconductor for the energy band diagram shown in the figure?

The correct option is (B) P-type semi-conductor.
