Exciton physics: basic to advanced
·
Module 5
Symmetry, Fine Structure, and Spectroscopy
1
Electron-Hole Exchange Interaction: Derivation and Contributions
Derive the electron-hole exchange interaction Hamiltonian, separating short-range and long-range contributions.
2
Exciton Formation and Exchange Splitting
Analyze the formation of optically active ortho-excitons (triplet) and dark para-excitons (singlet) from exchange splitting.
3
Exciton Transitions in Cubic Crystals: A Group Theory Approach
Apply group theory and character tables to determine dipole-allowed and forbidden exciton transitions in crystals with cubic symmetry (e.g., Cuâ‚‚O).
4
Exciton Fine Structure: Crystal Field and Spin-Orbit Coupling
Describe how crystal field and spin-orbit coupling modify the exciton fine structure.
5
Ortho- and Para-Excitons in Absorption and Photoluminescence
Analyze experimental signatures of ortho- and para-excitons in absorption and photoluminescence spectra.
