What is extrinsic conductor?
Impure semi conductor material are called extrinsic semi conductor as there a small quantity of foreign particle is present. Two types of impurities are added to an extrinsic semi conductor. When impurities belonging to third group are called as trivalent or acceptor impurities such as boron, aluminum, indium or gallium when these impurities are added in pure semi conductors they form p-type semi conductor. And similarly when impurities belonging to group fifth called as penta valent or donor impurities such as arsenic, antimony, bismuth or phosphorus are added to a semi conductor they form N-type semi conductor .
Explain the fermi level in intrensic and extrensic semi conductor?
chal bey
What are cold conductors?
A cold conductor is the insilation for a cold object to keep the coolness inside and the warmess out.
What is semi conductor diode?
Semiconductor diodes are made from the same Silicon, and occasionally Germanium, material that transistors, integrated circuits, etc. are made from. Diodes used in early electronic devices were made from vacuum tubes. Somewhat later diodes were made from finned stacks of Selenium. Simple "Crystal Radios" use Galena (lead ore) crystals with a steel pin that is manipulated to find a spot that allows electrical current to flow in only one direction.
What is the process in which trace amounts of other elements are added to a material to make it a semi conductor?
Doping.
How can you increase the conductivity of a semi conductor?
The conductivity of a semi-conductor can be increased by raising the temperature of the semi-conductor .
Is copper a conductor insulator or semi conductor?
Copper is a conductor.
Is a refrigerator an example of a conductor?
no
What are semi insulators?
A semi conductor is not a good conductor or a good insulator.
Which one is used in the laser printing wheather dye laser or semi conductor laser?

Is silver and gold such as jewelry, are they great semi conductor?
Yes, silver and gold are good semi conductor.
What are example of semi conductor?
Germanium and Silicon are the two most commonly known semi-conductor materials
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.

Why a soda can feels cold when you take it out of the refrigerator?
The aluminum material of the soda can is a conductor of heat, so it quickly absorbs the cold temperature from the refrigerator. When you touch the soda can, the coldness is transferred to your hand through conduction, making it feel cold to the touch.
Why soda can is cold when taken out of refrigerator?
When the soda can is placed in the refrigerator, it absorbs the cold temperature of the surrounding air and cools down. This causes the can to feel cold to the touch when you take it out of the refrigerator.
Why carbon isn't a good semi conductor?
Beg your pardon but Carbon is a good semi conductor - it is used in most small resisters.
