Influence of Crystal Structure on Resistance Switching Properties in TiO2 Films
摘要/Abstract
采用不同方法制备了4种不同相结构的TiO2薄膜：无定形、锐钛矿、金红石和混合相结构.通过对4种Ag/TiO2/Pt样品进行测试和分析发现，其阻变机制符合文献中报道的细丝模型.4种不同结构的样品均能够表现出阻变特性，均具有一定的保持性能和疲劳性能，其中锐钛矿样品具有相对较好的综合性能，其电阻转换比率达到2000%以上，保持性达到12K以上，疲劳性能也较稳定.
The TiO2 thin films with four different structures were prepared amorphous,anatase,mixed phase and rutile by using different methods.The resistive switching properties of these four heterostructrues were found consistant with the filaments mechanism.It was found that the resistance switching performance of these heteroostructrues can meet their applications in practice and all show better stability and fatigue property.Among these four heterostructrues,anatase sample showed a better performance,with its resistance switching performance being above 2000%,and its stability being above 12K,which shows its fatigue property is steady.
