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.

Where does the charge concentrate in a semiconductor?
In a semiconductor, the charge concentrates at the bounds of the space charge region(depletion layer).
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.
What is the thickness of the depletion layer in a semiconductor?
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.
What are the effect of depletion of ozone layer on man?
Depletion of ozone layer causes:Suppression of immune systemSkin cancerEye cataract.
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.
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.
What is the causes and effect of depletion in the ozone layer?
Depletion of ozone has many causes and effects. The UV entering is the main.
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 is the greenhouse effect the cause of the ozone layer depletion?
The greenhouse effect causes ozone depletion. Greenhouse doesn't let the heat escape, causing problems for ozone.
Is the depletion of ozone layer related with greenhouse effect?
The depletion of the ozone layer and the greenhouse effect are related but separate issues. The depletion of the ozone layer allows more ultraviolet radiation to reach Earth's surface, leading to increased skin cancer rates and other health problems. The greenhouse effect, on the other hand, refers to the trapping of heat in Earth's atmosphere by greenhouse gases like carbon dioxide, which contributes to global warming. Both issues are important environmental concerns.
How ozone layer is damaged by greenhouse effect?
Global warming causes greenhouse effect. It then causes ozone depletion.
Which layer of the atmosphere is affected the most during Diwali?
The stratosphere. there's a theory call stratospheric ozone depletion that causes the greenhouse effect and global warming and depletion if the ozone layer
