The thickness of the depletion region or depletion layer (and there are other terms) varies as the design of the semiconductor. The layers in a semiconductor are "grown" (usually by deposition), and this can be controlled. The typical depletion region thickness in an "average" junction diode is about a micron, or 10-6 meters. Junction "construction" presents major engineering considerations to those who design and make semiconductors as there are many different kinds. A link is provided to the section on the width of depletion regions in the Wikipedia article on that topic.

Where does the charge concentrate in a semiconductor?

How a semiconductor layer thickness measured?
A semiconductor layer thickness is typically measured using techniques such as ellipsometry, profilometry, or atomic force microscopy. These methods involve analyzing the interaction of light, surface topography, or surface force in order to determine the thickness of the semiconductor layer.
What is critical layer thickness?
The critical layer thickness is the minimum thickness of a strained layer needed to prevent dislocations from forming at the interface between the layer and the substrate. It is an important consideration in semiconductor device fabrication and thin film growth, as exceeding this thickness can lead to defects and degrade the performance of the material.
How does doping effect the depletion layer in semiconductor?
Width of depletion layer is given by x = (2*ebsylum*Vb).5/(qN) x = width Vb = potential barrier q = charge of electron N = doping concentration. Thus increase in doping will reduce width of depletion layer.
How temperature effects depletion layer width?
As temperature increases, the depletion layer width in a semiconductor decreases due to the increased thermal energy disrupting the balance of charges within the material. This disrupts the formation of the electric field that maintains the width of the depletion layer, causing it to shrink. Conversely, at lower temperatures, the depletion layer tends to widen as charges are less mobile and the electric field is more pronounced.
Why does the thickness of the ozone layer change seasonally?
Yes it does. It is because depletion takes place in winters only.
What is the depletion layer in a semi conductor?
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.
How the depletion width effected If the impurity concentration is incresed?
As impurity concentration increases in a semiconductor, the depletion width decreases. This is because a higher concentration of dopants leads to a greater number of charge carriers, which enhances the electric field within the depletion region. Consequently, the potential barrier is more effectively neutralized, resulting in a thinner depletion layer. This effect is critical in determining the electrical characteristics of semiconductor devices like diodes and transistors.
What effect of depletion layer by biasing?
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,
How depletion layer is thin?
The depletion layer is thin yet. But if we continue using CFC, it will be more.
Is the depletion of the ozone layer nature friendly?
No it is not nature friendly. Depletion of ozone layer is harmful.
