Exposing a semiconductor to light can generate electronhole pairs, which increases the number of free carriers and its conductivity.

Charge trapping centers that scatter free carriers form in many cases due to defects associated with dangling bonds. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Scattering happens because after trapping a charge, the defect becomes charged and therefore starts interacting with free carriers.

The energy difference in the ionization energy acceptor and the electron affinity of the donor leads to a charge transfer and consequently to free carriers whose number is normally fixed.

Multiple studies have shown that intermixing takes place at the interface; however, it is not clear whether there is enough intermixing to provide all of the free carriers.

In dielectrics or polymers, the free carriers are absent and absorption of photon below band-gap radiation takes place inside of the lattice. The above highly nonlinear electromagnetic processes in semiconductors are due mainly to the nonlinear response of the free carriers interacting with the external field.
