t(r, ze, z) = 1 4e(Ze)h(Zh)Q(r) (3
We choose 9(r) = 2/a0e-r/ao as a trial wavefunction, and then minimize the
energy of the exciton using the exciton Bohr radius ao as the variational parameter:
Eex = min ( IHIP)
=min [f9* (He + Hao- F (Ze - zh) (4.3.10)
- T I dr dze dzh
E1r2 -+ (Ze -Zft)2
While this minimization problem seems quite complex, it turns out that the only
portion of the integral which varies with ao is the excitonic portion of the Hamiltonian, -
e2/E 112. The other parts of the Hamiltonian depend only upon the z components of the
