项目摘要
Electron-transport mechanisms of oxide ceramics exhibiting high-speed voltage-pulse-induced resistivity changes were characterized with regard to nanostructure and defect formation. La-doped SrTiO_3 single crystals with Ag top electrodes and Pt bottom electrodes exhibited bipolar resistive switching but retained the low-resistivity state for only 3 or 4 hours because of unstable deep-level trap states at the metal-semiconductor interface. Crystalline (Pr^(0.7)Ca^(0.3)) MnO_3 thin films sandwiched by Pt electrodes showed metallic conductivity and consequently never showed electric-pulse-induced resistivity changes, but insulative amorphous (Pr^(0.7) Ca^(0.3)) MnO_3 thin films showed monopolar resistivity switching that suggested the formation of nanoscale filament paths with nanodomain switches. The TiO_2 anatase nanolayer formed on a TiN thin film exhibited high-speed electric-pulse-induced bipolar resistivity changes thought to be due to a Mott transition caused by O^(2-) migration and the formation and annihilation of Vo-in 2.5-nm-thick anatase layer.
氧化物陶瓷表现出高速电压脉冲诱导的电阻率变化的电子传输机制的特点与纳米结构和缺陷的形成。采用Ag顶电极和Pt底电极的La掺杂SrTiO_3单晶表现出双极阻变,但由于金属-半导体界面处的深能级陷阱态不稳定,其低阻态仅能保持3 ~ 4小时。晶态(Pr^(0.7)Ca^(0.3))MnO_3薄膜夹在Pt电极中显示出金属导电性,因此不会显示电脉冲引起的电阻率变化,但绝缘非晶态(Pr^(0.7)Ca^(0.3))MnO_3薄膜显示出单极电阻率开关,表明形成了具有纳米畴开关的纳米丝路径。在TiN薄膜上形成的TiO_2纳米层表现出高速电脉冲引起的双极性电阻率变化,这被认为是由于O^(2-)迁移引起的Mott转变以及2.5 nm厚TiO_2纳米层中VO-的形成和湮灭。
