Resistivity of a silicon

  1. Sep 8, 2007 #1
    1. The problem statement, all variables and given/known data
    A silicon sample is doped with 5.0 X 10^19 donor atoms/cm^3 and 5.0 X 10^19 acceptor atmos/cm^3

    a)What is its resistivity?
    b)Is this an insulator, conductor or semiconductor?
    c)Is this intrinsic material?
    2. Relevant equations
    No clue.. this is where I need help


    3. The attempt at a solution
    The question completely threw me off.

    I am assuming I can answer b and c once I calculate part a, but I have no clue which equation to use. Can anybody start me off?

    Sorry, Amazon still hasn't sent me the textbook yet, so I had a hard time doing the homework, searching through internet, which led me to this website at end :(

    Thanks for your help
