| Annotation | Investigations of the thermally stimulated luminescence of zinc oxide nanowires grown from a vapor phase were performed in the temperature range 295-480 K. The basic parameters of the trapping centers, such as the ionization energy of the traps, the capture cross section of the charge carriers traps and the frequency factor, were determined. The calculated values were found to be 0.320.03 еV, 6·10 – 18cm 2 and 1.9·106 s – 1, respectively. It was concluded that the green band in ZnO can be related to the electronic transitions from donor levels Zni to the acceptor levels VZn. |
