Deep levels nonradiative

Recombination at and excitation from deep levels are emphasized. Nonradiative transitions at defect levels—Auger, cascade capture, and multiphonon emission processes—are discussed in detail. Factors to be considered in the analysis of optical cross sections which can give information about the parity of the impurity wave function and thus about the symmetry of a particular center are reviewed. [Pg.352]

Despite the success of purely optical methods such as luminescence and absorption in studying shallow energy levels, they are seldom used for characterization of deep states. This is mainly because the deeper levels of interest are usually nonradiative ones or killer centers for which such techniques are not applicable. In addition, the deep position within the energy gap means optical experiments must be performed in the infrared where... [Pg.7]
