we know that relation in semiconductor is
conductivity proportional to temp
especially in extrinsic semiconductor holes or electrons are charge carriers .
in extrinsic semiconductor when temp is increased then the energy of charge carriers also increases.
now kinetic energy equall to [ (1/2) m v^2 ]
in this M is constant
this implies energy prop to square of velocity
therefore if conductivity of charge carriers increases while increasing of temperature
What else can I help you with?
Why are tin and lead not used as semiconductor?
because they are not semiconductors. They are metals and rather good conductors.
Materials that are not good conductors or and not good insulators are called?
Semiconductors. They have conductivity between conductors and insulators and are used in electronic devices like transistors and diodes.
Why do you use semiconductor why not conductors and insulators by changing their properties?
We use semiconductors instead of conductors and insulators by changing their properties because the properties of a semiconductor lies between that of a good insulator ant that of a good conductor. Any of the materials obtained depends on the level of doping.
Is sphalerite a good conductor of electricity?
No, sphalerite is not a good conductor of electricity. It is classified as a semiconductor, meaning it has some conductivity but not as high as good conductors like metals.
Which is a good conductor (Extrinsic or Intrinsic)?
Extrinsic
Is sliver a good semiconductor?
A: It not a semiconductor at all but it is a very Good conductor.
Is gold a semiconductor?
No, gold is not a semiconductor. It is a good conductor of electricity.
Are good or poor conductors better emitters?
good conductors are better emitters
What are two good conductors?
Metals are good conductors of electricity, two of the best conductors are silver and copper.
Good conductors of electricity are often good conductors of heat?
Generally speaking, materials that are good conductors of heat are good conductors of electricity. But there is a notable exception. Diamond, an allotrope of carbon, conducts heat better than any metal, but it is an electrical insulator.
What large group of materials are good thermal conductors and good electrical conductors?
metals
What are good conductors of electriicity?
Metals, in general. Copper and silver are particularly good conductors.
