Exercise: Activation of Mg acceptors in GaN. Mg acceptors in GaN have an activation energy of E₁= 200 meV. (a) Calculate the fraction of acceptors that are ionized at 300 K for an acceptor concentration of NM = 10¹8 cm³ using the formula p = (g¹NN+)¹2 exp(-E₂/2kT) where g is the acceptor ground state degeneracy (g = 4) and N, is the effective density of states at the valence band edge of GaN. (b) What would be the activation of acceptors if a hydrogen atom were bonded to each acceptor?
