An increase in the energy of the photodetachment of holes from A + centers with increasing acceptor concentration NA was observed in p-Si at NA = 1015-1017 cm-3. The effect is attributed to the influence of the field of the negatively charged acceptors on the Α + centers and to hopping of the holes over the neutral impurities.
