| Résumé: | A comparative analysis of transient photoconductivity in microgranular ZnO and ZnO nanowires prepared by oxidizing bulk ZnTe and ZnTe nanowires, respectively, is performed in this paper. The measurements are carried out at different temperatures in microgranular ZnO and at room temperature in the ambient air in ZnO nanowire networks. The mechanisms of photoconductivity decay are discussed taking into account the morphological features of the samples and the range of measured relaxation times. |
