| 英文摘要 | Structural and electrical behavior of Al2O3 doped ZnO-based ceramics were investigated as function of the aluminum doping ratios under reducing sintering atmosphere (N-2 + CO). With Al2O3 doping from 0.1 mol% to 0.55 mol%, the electrical conductivity increases firstly to a maximum (1.52 x 10(5) S.m(-1)) at 0.25 mol%, and then decreases gradually. The increased conductivity is explained by the formation of shallow donors as Al-zn-Zn-i complexes with doping to 0.25 mol%. As Al(2)O(3 )doping further increasing to 0.55 mol%, ZnAl2O4 spinel phase and more ZnO-ZnO grain boundaries are formed, hindering charge carriers transport, to decrease charge carrier mobility, thus to decrease the conductivity of ZnO ceramics. Therefore, the Al-zn-Zn, complexes, grain boundaries and ZnAl2O4 spinel can be adjusted by doping different Al2O3 amount, thus the carriers' concentration and their mobility are optimized to increase the conductivity. Our work, as a fundamental research, is of great significance to control conductivity by regulating Al2O3 doping. |
