Abstract | Undoped melt grown n-type ZnO single crystal (n1016cm-3) was irradiated by
1.7-MeV electrons with fluence of 1014 cm-2 followed by post-irradiation annealing. Au Schottky
contacts were thermally evaporated onto the samples with hydrogen peroxide pre-treatment.
Deep level transient spectroscopy measurement was used to investigate the deep traps induced
by the electron irradiation. The dominant trap in the as-grown ZnO single crystal has the
activation energy of 0.28eV. The electron irradiation introduced an extra trap having the
activation energy of 0.16eV. Thermal annealing study was also performed to study the thermal
evolution of these deep level defects. |
