SUMMARY
Excitons in semiconductors are defined as bound electron-hole pairs, exhibiting significant Coulomb interaction energy. The Bohr radius of a silicon exciton is approximately 5nm, representing the mean distance between the electron and hole, analogous to the hydrogen atom model. This radius is derived from the Rydberg-type model, which applies to excitons in terms of their energy and orbital states. Understanding these concepts is crucial for exploring exciton dynamics in semiconductor materials.
