Calculating the effective mass

  1. May 2, 2015 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations

    3. The attempt at a solution
    I understand you can calculate the effective mass by using the equation above. What I'm unsure about is the "calculate the effective mass of the carriers" part. A donor impurity would be near the conduction band, therefore do we simply use the equation for Ec in the question? A bit unsure.

    I would expect that, but I'm not sure.
