What do you mean by depletion region of a diode?

Depletion region or depletion layer is a region in a P-N junction diode where no mobile charge carriers are present. Depletion layer acts like a barrier that opposes the flow of electrons from n-side and holes from p-side.

What is depletion region Ncert?

When an electron diffuses from n to “p”, it leaves behind a positive charge on the n-side. This space-charge region on either side of the junction together is known as the depletion region as the electrons and holes taking part in the initial movement across the junction depleted the region of its free charges.

What is depletion region Quora?

Depletion region. It is a insulating region with in a conductive , doped semiconductor material where the mobile charge carrier have been diffused away or have been forced away by an electric field. The only elements left in the depletion region are ionized donor or acceptor impurities.

What is the depletion region in a PN junction?

The region of positive charge and negative charge on either side of the junction is termed as the depletion region.

What is depletion region?

In semiconductor physics, the depletion region, also called depletion layer, depletion zone, junction region, space charge region or space charge layer, is an insulating region within a conductive, doped semiconductor material where the mobile charge carriers have been diffused away, or have been forced away by an …

Why is depletion region formed?

The depletion region is caused by the diffusion of charges. The holes and the electrons diffusing towards each other combine near the junction. In doing so positive and negative ions are formed. The pair of positive and negative ions at the junction forms the dipole.

How is depletion region formed Class 12?

The depletion region is caused by the diffusion of charges. Because of the concentration gradient holes diffuse from p-side to the n-side across the junction while electrons diffuse from the n-side to the p-side. The holes and the electrons diffusing towards each other combine near the junction.

Why depletion region is called so?

Answer: When diode is in reverse bias condition ,charge carriers (holes and electrons) tends to move away from the pn-junction ,leaving behind immobile ions at the junction. This formation of junction is called depletion region as it has negligible charge carriers or is depleted of free charge carriers.

What happens in depletion region?

How is a depletion region formed?

What is depletion layer Class 12?

Depletion layer is the region created around the p-n junction which is devoid of free charge carriers and has immobile ions.It is created due to diffusion of majority carriers across the junction when p-n junction is formed.

Is depletion region neutral?

There isn’t any neutral region in the depletion region.

What is the depletion region?

Depletion region or space charge region is a space where there are ions and atoms but no electrons to conduct. Alternatively, they can also imply an electron cloud around a principal electron emitter, which prohibits the emission and/or motion of further electrons to the other electrode.

What is depletion region in semiconductor materials?

In semiconductor physics, the depletion region, also called depletion layer, depletion zone, junction region, space charge region or space charge layer, is an insulating region within a conductive, doped semiconductor material where the mobile charge carriers have diffused away, or have been forced away by an electric field.

What elements are left in the depletion region of an IC?

The only elements left in the depletion region are ionized donor or acceptor impurities. In semiconductor physics , the depletion region also called depletion layer , depletion zone , junction region , space charge region or space charge layer.

What is the depletion region of a diode?

Depletion Region: In semiconductors, the depletion region is the layer where the flow of charges decreases. This region acts as the barrier that opposes the flow of electrons from the n-side to the p-side of the semiconductor diode
