What is doping process?
It is the addition of impurities to a semi-conductor in order improve their electrical conductivity.
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
Which semiconductor have positive temperature coefficient?
With the increase in temperature if the resistance increases or the current in the circuit decreases then it is said to be have positive temperature coefficient .But in semi-conductors with the increase in temperature the electrons present in the valance band are excited and they would enter the conduction band for conduction . As the no. of charge carriers always increase in a semi-conductor , implies that the current always increases with the increase in temperature so the semi-conductor can never have positive temperature coefficient
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
What does the skin effect increase in a conductor?
line losses tend to increase
Is silicon a good conductor at energy?
semi conductor. a good semi conductor. It can also be n or p doped to increase it's conductivity
Is sodium a semi conductor?
No, sodium is a metal and is not a semiconductor. Semiconductors are materials that have conductivity between that of a conductor and an insulator. Sodium is a good conductor of electricity due to its metallic properties.
What is the needed for doping?
To increase the conductivity of semi conductors
What is doping process?
It is the addition of impurities to a semi-conductor in order improve their electrical conductivity.
How do you increase the conductivity of a semi conductor?
You can increase the conductivity of a semiconductor by doping it with impurities to increase the number of charge carriers (electrons or holes). This can be done by adding elements that provide extra electrons (N-type doping) or by adding elements that create holes (P-type doping). Additionally, raising the temperature can also increase the mobility of the charge carriers, thereby increasing conductivity.
Is aluminium conductor or semi conductor?
Aluminum is a conductor of electricity. It is commonly used in electrical wiring and transmission lines due to its high conductivity.
What is the difference between insulator and bad conductor and semi conductor?
an insulator doesn't allows electricity pass from it, a bad conductor allows electricity to pass from it but not fully or completely and a semi conductor pass electricity in little form which used to operate electronics
IS PERSPEX A SEMI CONDUCTOR?
No, Perspex is not a semiconductor. It is a type of transparent plastic material known as polymethyl methacrylate (PMMA). Semiconductors are materials that have conductivity between that of a conductor and an insulator.
How can you make a poor conductor into a better conductor?
To make a poor conductor into a better conductor, you can increase its conductivity by adding impurities or doping materials, applying heat to increase kinetic energy of charge carriers, or reducing its length to decrease resistance. In general, manipulating factors that affect conductivity such as temperature, impurities, and length can improve a material's ability to conduct electricity.
Is bismuth a semiconductor or conductor?
the band structure of bismath suggests a low density of conduction electrones and holes,so it is semi conductor
Is doping is used to increase the conductivity of intrinsic semi conductor material?
Doping a semiconductor provides additional charge carriers to the material. The dopant atoms are easily ionized, and this provides the semiconductor with either free electrons in the conduction band or electron vacancies (or holes) in the valence band, both of which allow the semiconductor to conduct electricity.
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
