Charge carrier density

  1. Jun 3, 2005 #1
    I've been trying to find a formula for calculating charge carrier density of a material, or a table of values , but can't seem to find any. If anyone knows of a link to a formula or table, any help would be welcome.

    there's no general formula since metals and semiconductors have very different properities. did you have metals or semicondutors in mind or both?

    haha. we used that page at a solid state physics course I took.

    Baby, hit me one more time.

    I was actually wondering about graphite, ex70 in particular (1.85 g/cm2).

    Basically, I'm trying to find good materials for a Hall probe project I'm working on, and I'm considering what I have laying around, but can't find values for anything I have.

    I find this
    In TaN, each Ta atom contributes three electrons to the N 2p band and two electrons to the 5d conduction band, resulting in a charge carrier density n = 9.7 X 10to power 22 cm−3
    how? any idea?
