The equilibrium and nonequilibrium electrical conductivity of synthetic diamond is studied in the temperature range 300-400 K in weak and strong electric fields. Its optical characteristics are also investigated. It is found that two types of local centers appear in nonequilibrium processes: acceptors with the level Ev +0,4 eV and donors with a level approximately in the middle of the bandgap. Both dark conductivity and photoconductivity are transported by holes. It is observed that the depth of the acceptor centers is reduced in a strong electric field, which may be caused by field ionization of excited states of a hydrogen-like center. (text)
