Abstract(in English) | We have investigated effects of Bi content on electrical properties of SrBi_2Nb_2O_9(SBN) thin films. The SBN films were deposited with co-sputtering method in situ on p-type Si (100) substrates. In order to control the Bi/Sr content ratio, we used SrNb_2O_6 and Bi_2O_3 targets with different powers of RF magnetrons. We have found that electrical properties are strongly sensitive to the Bi content. The memory window gradually increased with increasing the Bi/Sr ratio in the SBN thin films, but when the Bi/Sr ratio was over 3.1 the electrical properties such as memory window and breakdown voltage were degraded. The memory window of the Pt/SBN/Si ferroelectric gate structure with the Bi/Sr ratio of 3.1 was 1.8 V ar applied voltage of 3V. And the leakage current density was 4.74×10^<-8> A/cm^2 at applied voltage of 3V. |
