摘要：

Ferroelectric properties and the effect of Li+ and Mg2+ dopants in II-VI semiconductor ZnO were studied. The ferroelectric D-E loops were observed in Zn1-x (Li-0.02. Mgx-0.02)O, as well as in Zn1-xLixO. The transition temperature (T-c) increases in proportion to the concentration of Mg2+ ions, while it is almost constant (330 K) in Zn1-xLixO above x > 0.1. T-c was 260 K for Zn-0.9 (Li0.02Mg0.08)O and 360 K for Zn-0.7(Li0.02Mg0.28)O. An additional 20% of Mg increases T-c by 100K. The ferroelectric phase transition is strongly influenced by the introduction of small Li and Mg atoms instead of the host Zn atoms in wurtzite ZnO.
