Re: What is an instrinsic conductor, and what is an extrinsic conductor?

Technically, there are no intrinsic or extrinsic conductors.  Intrinsic 
and extrinsic conduction are terms that are applied to semiconductors.  
These terms refer to methods of enhancing the conductivity of 
semiconductors.  The conductivity of semiconductors arising from thermal 
excitation is called intrinsic conductivity.  Another way to increase the 
conductivity of a semiconductor is by doping -- the addition of 
impurities.  After doping, the resulting conductivity is called extrinsic 
conductivity.

Thanks for the question! I hope this helps.
