How depletion region is formed in pn junction?
Movement of electrons to the p-type side exposes positive ion cores in the n-type side while movement of holes to the n-type side exposes negative ion cores in the p-type side, resulting in an electron field at the junction and forming the depletion region.
What is depletion region in a PN junction show with a diagram?
The two space charge regions on either side of the junction is called as depletion region. A potential difference is developed across the junction of two regions, which is known as the barrier potential. The reverse polarity of this potential opposes further flow of carriers.
What is depletion layer in PN junction?
Depletion layer- Depletion layer created by the initial movement of majority carrier across the junction.
What is the depletion region of a p n junction 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 Answer verified by Toppr Upvote (49)
What is depletion layer in p-n junction diode?
A potential difference built across the p n Junction, which restricts the further movement of charge carriers across the junction, is known as Potential Barriers. Depletion Layer. A layer is formed on both the side of the junction. This layer is depleted of free electrons and holes .
What does depletion region mean?
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 diffused away, or have been forced away by an electric field.
