Abstract: | Irradiation of zinc oxide single crystals with fast electrons produces both interstitial ions and vacancies. ESR investigations supply knowledge about the local structure of these intrinsic centres. The characteristic photosensitivity of the ESR spectra has been studied in detail. The electron configurations are discussed under the conditions of the covalent ZnO bond. A band model is proposed to explain the observed photosensitivities. |
