Semiconductor intrinsic Fermi Level? Bandgap Energy?

  1. Oct 15, 2015 #1
    equation (2.6.24)


    we have this equation for fermi level, but I wonder how this works though?
    In the lecture, we assumed Ec=Eg and Ev=0 to get E_gap/2.

    but I wonder how (Ec+Ev)/2 actually gives E_gap/2 instead of Ec-Ev=Eg

    It was a stupid question. sorry.
