E-K diagram assistance.

  1. Dec 26, 2013 #1
    Hello,
    1. The problem statement, all variables and given/known data
    I'd like to draw the E-K diagram for the following within the first brillouin (-π/a≤k≤π/a):
    Conduction band: E(k) = E0 + Ak2 - Bk4
    Valence band: E(k) = Ccos(ka)
    Where E0=1.48eV; C=0.3eV; B=2.78*10-31eVcm4; A=1.69*10-15eVcm2


    2. Relevant equations



    3. The attempt at a solution
    Should I simply plug in some arbitrary values within the specified domain? How ought this to be approached?
