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 .
Why is silicon a good heat conductor but a poor electrical conductor?
Metals are actually good conductors of both heat and electricity... but silicon is a semi-conductor. Unlike metals, which are good electrical and heat conductors, crystalline solids such as diamond and semiconductors such as silicon are good heat conductors but poor electrical conductors. This is their nature... you can't change it :-)
What is the normal engine temperature for a semi?
160 to 185 degrees F is normal running temperature.
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
Is sodium a semi conductor?
No, sodium (Na) is a conductor not a 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
Is copper a conductor insulator or semi conductor?
Copper is a conductor.
What is the state of semi metals at room temperature?
At room temperature all metalloids are solid.
Why GaAs is preferred to Si for high temperature operation of semi-conductor device?
GaAs has high mobility compare to Si
Is a cotton shirt a insulator or conductor?
semi conductor
Which one is used in the laser printing wheather dye laser or semi conductor laser?
