Exciton physics: basic to advanced
·
Module 2
The Wannier-Mott Exciton Model
1
Center-of-Mass and Relative Coordinates for Two-Particle Systems
Separate the center-of-mass and relative coordinates for a two-particle system to formulate the exciton problem.
2
Excitons: Screened Coulomb Potential & Rydberg Series
Solve the hydrogen-like problem for an electron-hole pair with a screened Coulomb potential to derive the exciton Rydberg energy series and Bohr radius.
3
Dielectric Screening and Exciton Binding Energy
Analyze the role of dielectric screening on exciton binding energies in different material classes.
4
Wannier-Mott vs. Frenkel Excitons: A Criterion for Distinction
Derive and apply the criterion distinguishing Wannier-Mott excitons from tightly-bound Frenkel excitons.
