What is whole current in p type semi conductor?
In semiconductor two charge carriers are present i.e holes and electrons.The current is rate of flow of charges.so in ptype semiconductor the current is the sum of current due to holes and electrons.But current due to holes is more compsred to electrons in ptype.
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.
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 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?
semi-conductor
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.
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 .
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.
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
