in correct sense it is not the layer but the region around the metallurgical junction which is depleted of charge carriers .in this region an internal electric field exist which counter balance the diffusion of electron and hole around the junction .
basically the main reason for the formation of depletion region is the concentration gradient across metallurgical junction of p-n semiconductor.
Impure semi conductor material are called extrinsic semi conductor as there a small quantity of foreign particle is present. Two types of impurities are added to an extrinsic semi conductor. When impurities belonging to third group are called as trivalent or acceptor impurities such as boron, aluminum, indium or gallium when these impurities are added in pure semi conductors they form p-type semi conductor. And similarly when impurities belonging to group fifth called as penta valent or donor impurities such as arsenic, antimony, bismuth or phosphorus are added to a semi conductor they form N-type semi conductor .
It is a shielded high voltage cable made up of center conductor with the next layer being a semi-con layer followed by a insulation layer with another layer of semi-con wrapped with a copper stranded ground and covered by a protective jacket. It is usually three wires, each carrying a phase of the three phase primary that most power companies generate today.

Semiconductor diodes are made from the same Silicon, and occasionally Germanium, material that transistors, integrated circuits, etc. are made from. Diodes used in early electronic devices were made from vacuum tubes. Somewhat later diodes were made from finned stacks of Selenium. Simple "Crystal Radios" use Galena (lead ore) crystals with a steel pin that is manipulated to find a spot that allows electrical current to flow in only one direction.
The conductivity of a semi-conductor can be increased by raising the temperature of the semi-conductor .
on forward biasing width of the depletion layer decreases whereas on reverse biasing the width of depletion layer increases.
Ozone layer depletion is the depletion of ozone. It has very bad affect on environment,
The depletion layer is thin yet. But if we continue using CFC, it will be more.
No it is not nature friendly. Depletion of ozone layer is harmful.
Ozone layer depletion is the thinning of ozone layer. It is most evident over the poles on earth.
Depletion layer The area in a P-N junction that is free of (i.e., depleted of) current carriers.
The ozone depletion is the thinning of ozone layer. It is most prominent over Antarctica.The ozone depletion is the thinning of ozone layer. It is most prominent over Antarctica.
Copper is a conductor.
Depletion of ozone layer only brings bad to environment. UV enters and thus causes depletion to ozone.
Ozone layer depletion takes place on PSC's. These are frozen clouds.
Depletion of ozone layer causes:Suppression of immune systemSkin cancerEye cataract.
