Conductivity problems

  1. May 31, 2005 #1
    Can someone help me with the following questions?
    1. How does temperature affect the # of charge carriers in a semiconductor? Explain
    2. The # of ______ electrons is equal to the # of electrons available for conduction. Why?
    3. How do dislocations affect the mobility of electrons in metals?

    If anyone can help me I would be eternally grateful

    There is a nice discussion of electrical properties and materials, specifically Electrical Conduction, at - http://www.virginia.edu/bohr/mse209/chapter19.htm

    A dislocation represents a distortion in the crystal lattice, and electrons are scattered by discontinuities in the material lattice.

    The electrons with the least binding energy would be most readily available for conduction.
