Homework Help: Model semiconductor -> calculate charge density, electric field, electric potential

  1. May 3, 2010 #1
    1. The problem statement, all variables and given/known data

    Consider a model semiconductor with a bandgap of 1.0 eV which is doped with 10^17 /cm^3 acceptors for x<0 and 10^17 /cm^3 donors for x>0.

    E_c - mu = 0.1 eV on the far left and on the far right (far from x=0)

    2. Relevant equations



    3. The attempt at a solution

    there seems to be something wrong with the problem statement above. what needs to be changed? what additional information is needed in order to calculate the charge density, electric field, and electric potential as a function of X?
