Exciton physics: basic to advanced
·
Module 10
Excitonic Complexes: Trions and Biexcitons
1
Trion Formation and Binding in Semiconductors
Describe the formation and binding of trions (charged excitons) in doped or gated semiconductors.
2
Biexciton Hamiltonian Formulation
Formulate the four-particle Hamiltonian for a biexciton (excitonic molecule).
3
Estimating Biexciton Binding Energies Using Variational Methods
Apply variational methods with appropriate trial wavefunctions to estimate biexciton binding energies.
4
Biexciton Selection Rules in Two-Photon Processes
Derive the selection rules for biexciton creation via two-photon absorption and decay via radiative cascade.
5
Distinguishing Biexciton vs. Exciton Emission via Power-Dependent PL
Analyze power-dependent photoluminescence spectra to distinguish biexcitonic emission from single-exciton emission.
