论文摘要
在这项工作中，使用所谓的喷雾热解过程，生长了LA1-XSRXCOO3（0.05 <x <0.26）化合物的薄膜。生长的薄膜表现出多晶微观结构，具有均匀的晶粒尺寸分布和可观察的孔隙度。关于它们的电运输特性，产生的薄膜表现出半导体样的行为，无论SR掺杂水平如何，这很可能既可能是由于氧不足和膜的颗粒状性质所致。此外，室温电流电压（I-V）的测量显示稳定的电阻切换行为，这在太空充电有限的传导机制方面得到了很好的解释。提出的实验结果提供了有关低成本，工业尺度的参与的基本证据，用于在随机访问存储器设备中的潜在应用，该方法的生长钙钛矿过渡金属氧化金属薄膜。
In this work thin films of the La1-xSrxCoO3 (0.05 < x < 0.26) compound were grown, employing the so-called spray pyrolysis process. The as-grown thin films exhibit polycrystalline microstructure, with uniform grain size distribution, and observable porosity. Regarding their electrical transport properties, the produced thin films show semiconducting-like behavior, regardless the Sr doping level, which is most likely due to both the oxygen deficiencies and the grainy nature of the films. Furthermore, room temperature current-voltage (I-V) measurements reveal stable resistance switching behavior, which is well explained in terms of space-charge limited conduction mechanism. The presented experimental results provide essential evidence regarding the engagement of low cost, industrial-scale methods of growing perovskite transition metal oxide thin films, for potential applications in random access memory devices.
