Does Recombination in semiconductors always result in production of photons?
When you excite a semiconductor you typically generate lots of electrons and holes. When studied in detail they will have a rich dynamic, as there are several recombination paths, as you mention in yo …

Fermi-Dirac distribution - holes and electrons
To answer your question we have to keep in mind, that holes are quasi particles. They are a mathematical formalism. They are introduced as empty states in the valence band. From a physical point of vi …

How can electrons travel from the valence band into the conduction band?
The idea that the electron travels on the energy axis is a misconception. Every state in the valence band $\phi_{VB}$ corresponds to a wave function and thus a probability distribution in space. The s …
