Charge at Dielectric-Conductor Interface

  1. Oct 22, 2008 #1
    Say I have a capacitor filled with a linear dielectric in a purely electrostatic setup. Then there will exist a uniform electric field inside the capacitor, and the field inside the electrodes is of course zero. The dielectric will polarize, and I should get bound charge at the dielectric-conductor interface. It seems to me that you would also get some induced free charge from the conductor as well at this interface.

    What kind of coulomb forces would I get in this situation, if what I described is in fact correct?

    To generalize my question, what in general happens at a conductor-dielectric interface? How does the induce charge behave? Is there only surface polarization charge from the dielectric, or does induced free charge come into play from the conductor?
