What are the advantages of intrinsic semiconductor?
due to the poor conduction at room temperature,the intrinsic semiconductor as such,is not useful in the electronic devices.hence,the current conduction capability of the intrinsic semi conductor should be increased. this can be achieved by adding a small amount of impurity to the intrinsic semi conductor
What are the advantage of semiconductor over conductor?
semiconductors are the conducors they are partially conduct electricity. And we can increase therir conductivity by using various method . They are Intrinsic method and extrinsic method . Intrinsic method is heating the semiconducter . Extrinsic method is doping. By using this method the conductivity of semiconductors is rapidly increases. Then we use semiconductors are prefferd to conductors
Is pressure a extrinsic or intrinsic?
Intrinsic
What is Intrinsic Impedance?
intrinsic impedance is ratio of E/H from a uniform plane ve in a materal
Can a vacuum is conductor or non conductor?
A vacuum is a non conductor.
Which is a good conductor (Extrinsic or Intrinsic)?
Extrinsic

What is the net charge on intrinsic N type material?
first of all un-doped semi-conductor is said to be intrinsic semi-conductor so, there is no discussion of either N-type or P-type
Factors affecting intrinsic conductor?
temperature, mobility of electron hole as well as the mobility of electrons. It is also based off the boltzmann's constant and the Bandgap Energy value of the solid material used to make the intrinsic conductor
Is hematite a good conductor?
Hematite is a poor conductor of electricity due to its intrinsic electrical resistivity. While it does contain iron, which is a conductor, the crystalline structure of hematite results in poor electron mobility.
What is meant by intrinsic silicon?
Intrinsic silicon is pure silicon with no intentional impurities added. It has a balanced number of positive and negative charge carriers, making it an electrical insulator at room temperature. Intrinsic silicon is the base material used in semiconductor device fabrication.
Is resistivity depends upon dimension of conductor?
Yes, resistivity is dependent on the material of the conductor, not its dimensions. Resistivity is an intrinsic property of a material that influences its ability to resist the flow of electrical current.
The addition of arsenic to germanium makes the latter a an- a) Extrinsic semiconductor b) Metallic conductor c) Intrinsic semiconductor d) Mixed conductor?
The addition of arsenic to germanium makes it an extrinsic semiconductor (option a). This is because arsenic acts as a dopant, introducing free charge carriers (electrons) into the germanium, which enhances its electrical conductivity compared to intrinsic germanium.

Does resistivity depends upon dimension of the conductor?
Yes, resistivity does depend on the dimensions of the conductor. The resistivity of a material is an intrinsic property, but the resistance of a conductor is also influenced by its dimensions such as length, cross-sectional area, and shape. These dimensions affect the resistance of the conductor through the formula R = ρ * (L/A) where ρ is resistivity, L is length, and A is the cross-sectional area.
What is doping in conductor?
The process of adding suitable impurities in the intrinsic semiconductor is called doping. The impurity added to the intrinsic semiconductor to increase its conductivity is called dopant. There are some methods of doping in case of a conductor.impurity atoms can be added to the intrinsic semiconductor in different ways discussed below:A very small quantity of impurity atoms is made by diffusing into the high purity molten material such as germanium when the crystal is grown out of melt.Impurity atoms can also be added into the intrinsic semiconductor by heating it in the environment having impurity atoms.Impurity atoms can also be added into the intrinsic semiconductor by bombarding it with the impurity atoms.
Why intrinsic conductor not used in electronic devices?
Intrinsic semiconductors have small conductivity at the room temperature. and also if we raise the temperature to increase their conductivity then they will start acting merely like a conductor. and there will not be any control over the directions or the magnitude of the current flowing through it. so by mixing the suitable impurity(dopant) we obtain the extrinsic semiconductor. so that the conductivity as well as the control over the current can be increased. Although intrinsic semiconductor are also somwhere used in electronics where i high resistance layers or a separation layers b/t two systems is needed. like in PIN diode.
