Semiconductor luminescence equations

Semiconductor luminescence involves the emission of light (photons) from a semiconductor material, typically as a result of electron-hole recombination, where electrons from the conduction band recombine with holes in the valence band. The process can be described using several key equations and principles: 1. **Energy Band Model**: The electronic states in a semiconductor are often depicted in terms of a band structure, where the valence band and conduction band are separated by a band gap \(E_g\).
