recombination
- noun
- /ˌriːkəmˈbɪneɪʃən/
- Specialized
- When the electric field E exceeds a threshold, E > E_thr, the generation rate of new electrons from ionization exceeds their recombination rate, and the number of free electrons begins to exponentially increase.
- electron-hole recombination
- hydrogen recombination
- hole recombination
Examples
-
The minority carrier lifetime of a silicon wafer is related to the recombination activity on the surface of the wafer, considering a high enough bulk lifetime.

The two main candidates are a three-body reaction (with an extra e+ to carry off the binding energy) and radiative recombination.

In the lower atmosphere, the recombination lifetime for these ions is typically five minutes.
Academic text (1998) -
A fuel cell does the opposite: electricity is produced through the electrochemical recombination of hydrogen and oxygen gases to form water in its liquid state.
Academic text (2000) -
Subsequent exposure to visible light excites the traps and leads to recombination of electrons and holes and the release of visible light.

The many-electron-one-hole recombination process can also be influenced by the detailed subband energy level structure and by dimensionality effects.
Academic text (1994) -
In that early stage, one of the most important chemical processes is catalyzed by the small fraction of free electrons left over from recombination, an event that took place some tens of millions to 100 million years earlier.
Academic text (2011) -
The only light present before the epoch of recombination was the cosmic background radiation, a universal radiation permeating every nook and cranny.
Academic text (2004) -
The current's decay time t_d is determined by the electrons' recombination in three-body collisions and is inversely proportional to the square of the density of air molecules.
Academic text (2006) -
In the study of plasma physics, recombination occurs when ions and electrons unite to form neutral atoms, releasing energy in the process.

Etymology
Recombination starts with the prefix re- meaning 'again' and the root combine meaning 'to join together'. In physics, recombination is when charged particles join again to make neutral atoms, so the word describes the 'joining again' that often releases energy or light.
