recombination centre

https://doi.org/10.1351/goldbook.14081
Defect in semiconductors and insulators capable of sequential capture of free charge carriers of both signs with high efficiency.
Note: Provides a path for the recombination of free electrons and holes at high rates. Typically, in imperfect wide-bandgap energy solids, the rate of photoinduced carrier recombination through recombination centres at moderate photon irradiance is larger than the rate of band-to-band recombination.
