Growth and Structural Effect on the Electrical Transport of Epitaxial NiCo2O4 Thin Film

摘要/Abstract

摘要：

采用脉冲激光沉积技术在不同衬底材料上沉积了NiCo2O4（111）外延薄膜，分别利用反射式高能电子衍射、X线衍射及原子力显微镜表征了NiCo2O4外延薄膜的晶体结构和表面特征，测试了2种不同衬底材料上NiCo2O4外延薄膜的电输运性质，分析了薄膜的电输运有效激活能与温度的关系.研究发现，2种不同衬底上NiCo2O4外延薄膜的电输运性质具有完全不同的特征，且均表现出好的导电性.所得研究结果可以为NiCo2O4薄膜在自旋电子器件中的应用提供重要的实验指导和现实参考.

Abstract：

The rich physical and chemical properties of NiCo2O4 have attracted a lot of attention all over the world,but its intrinsic electrical and magnetic properties and its application in spintronic devices are not well established，and the further studies are needed to address these questions.In this paper,it was used pulsed laser deposition to deposit epitaxial NiCo2O4(111) thin film on different substrates,and reflection high-energy electron diffraction,X-ray diffraction,and atomic force microscopy are employed to characterize the structure and surface features of NiCo2O4 epitaxial films.The electrical transport properties of NiCo2O4 epitaxial films on different substrates were investigated,and the relationship between the effective activation energy and temperature was analyzed.The study has found that the electrical transport properties of NiCo2O4 epitaxial films on different substrates possessed completely different features,while all of these NiCo2O4 thin films have very excellent electrical conductivity.This study will provide important experimental guidance and practical references for the application of NiCo2O4 films in spintronic devices.
