Abstract
Four types of different center transformation processes enhanced by photoexcitation are given consideration. (1) Association of shallow donors with one another. (2) Dissociation of donor-acceptor pairs (DAP). (3) Donor migration from dislocations into the bulk of the crystal and association with acceptors. (4) Dissociation of complexes, consisting of several DAP and deep acceptors. It is shown that processes 1 and 4 are due to the recharge of defects under illumination and their further diffusion, whereas in processes 2 and 3 so-called "phonon kick" may take place together with recharge.
