Homework Statement
In chapter 8, page 207 Kittel derives an equation for the fermi level in an intrinsic conductor:
[tex]\mu[/tex]=½Eg + [tex]\frac{3}{4}[/tex]kBT*ln(me/mh)
How am I to understand the ln(me/mh) part? Earlier he states that the effective mass is proportional to the curvature of the energy band, and hence me = - mh.. thus it would be ln(-1) ?
