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?

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.
Where does the charge concentrate in a semiconductor?
In a semiconductor, the charge concentrates at the bounds of the space charge region(depletion layer).
Why deplition region is small in germanium?
The depletion region in germanium is small because germanium has a lower band gap compared to silicon. This results in a higher charge carrier concentration and a narrower depletion region. Additionally, germanium has a higher intrinsic carrier concentration, leading to a smaller depletion region.
What Depletion region will form?
A depletion region will form at the junction of a p-type and n-type semiconductor in a semiconductor diode. This region is depleted of charge carriers, creating an electric field that prevents further flow of current in the reverse bias direction.
How are N-type semiconductor used in semiconductor diode?
p-type semiconductor is obtained by carrying out a process of doping that is by adding a certain type of atoms to the semiconductor in order to increase the number of the free charge carriers.
Is a depletion region a good conductor?
No, a depletion region is not a good conductor. It is an insulating region formed in a semiconductor material when a voltage is applied, creating a barrier to the flow of current.
What are the causes of ozone deplition?
CFC's cause ozone depletion. They react with ozone to deplete it.
What is a difference between forbidden energy gap depletion region in semiconductor?
forbidden energy gap or energy gap or band gap or band or Eg is the gap between the top of the valance band and bottom of the conduction band. If we apply the energy equivalent to Eg then the electrons in valance band will jump to the conduction band.

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.
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.
