Depletion region: Consider a diode .It is a basic semiconductor.It has two regions .A cathode (Negative-N) and anode(Positiv-P) regions.The N and P when connected together forms a diode.A junction will be created at the intersection of N and p regions .N region has electrons(-ve charge) and P region has holes(+ve charge) .At the junction the electrons from N region and holes from P region will join together .Particular area at the junction will have no charged particles after that.This region is called depletion region. If we give a voltage of 0.7V ,the depletion region will decrease and there will be current flow in the device.That voltage is called thershold voltage.

What is a compensated semiconductor?
compensated semiconductor...SEMICONDUCTORS WHICH CONTAIN BOTH DONOR AND ACCEPTOR DOPANT ATOMS IN SAME REGION IS CALLED COMPENSATED SEMICONDUCTOR.
Is copper a conductor and a semiconductor?
Copper is a conductor but not a semiconductor.
What is the term for a semiconductor that is missing electrons?
p-type semiconductor A semiconductor that is missing electrons is called an electron hole.
How semiconductor diodes operates?
semiconductor diode with out a pn junction.
What will happen when doped semiconductor is heated will its conductivity increase or decrease?
Doping a semiconductor means to introduce impurities to the semiconductor in order to alter it. For the most part, doping a semiconductor increases its conductivity.
What is a compensated semiconductor?
compensated semiconductor...SEMICONDUCTORS WHICH CONTAIN BOTH DONOR AND ACCEPTOR DOPANT ATOMS IN SAME REGION IS CALLED COMPENSATED SEMICONDUCTOR.
Where does the charge concentrate in a semiconductor?
In a semiconductor, the charge concentrates at the bounds of the space charge region(depletion layer).
Is deplition of resourceis good?
No
Is the greenhouse effect made worse by the deplition of the ozone?
Yes, it is. The greenhouse effect is made worse by ozone deplition.
What are the causes of ozone deplition?
CFC's cause ozone depletion. They react with ozone to deplete it.
What is the meaning of piezo resistive sensors?
Piezoresistive sensor are the semiconductor sensors who respond to the change in the mechanical strain applied. For example, a p-type region diffused into an n-type base functions as a resistor whose value increases strongly when it is strained, this behaviour is called piezoresistivity. Such resistors are the basis of semiconductor strin gauges, semiconductor diaphragm pressure sensors and semiconductor accelerometers.
Which month has ozone deplition maximum?
Winters has the maximum ozone depletion. It is because of the low temperature.
Is sodium a semiconductor?
It is a semiconductor.
Is arsenic a semiconductor?
Arsenic is not a semiconductor by itself, but it is commonly used as a dopant in semiconductor materials like silicon to alter their electrical properties. Arsenic increases the number of available charge carriers in the material, which can make it conduct electricity more effectively.
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 is a semiconductor slice?
A semiconductor slice is used to make integrated circuits or ICs. It is also known as a semiconductor wafer or a semiconductor substrate.
Which gas has highest ozone deplition?
CFC gases depletes the ozone. Ozone holes have been created because of it.
