Abstract

This article focuses on the NaO-GaO-TiO system, which is barely explored in the study of transparent conductive oxides (TCOs). NaGaTiO (n = 5, 6, and 7 and x ≈ 0.7-0.8) materials were characterized using neutron powder diffraction and aberration-corrected scanning transmission electron microscopy. Activation energy, as a function of different structures depending on tunnel size, shows a significant improvement in Na ion conduction from hexagonal to octagonal tunnels. New insights into the relationship between the crystal structure and the transport properties of TCOs, which are crucial for the design and development of new optoelectronic devices, are provided.

摘要

本文聚焦于NaO-GaO-TiO体系，该体系在透明导电氧化物（TCOs）研究中几乎未被探索。使用中子粉末衍射和像差校正扫描透射电子显微镜对NaGaTiO（n = 5、6和7且x≈0.7 - 0.8）材料进行了表征。作为取决于隧道尺寸的不同结构的函数，活化能显示出从六边形隧道到八边形隧道的Na离子传导有显著改善。提供了对TCOs晶体结构与传输特性之间关系的新见解，这对于新型光电器件的设计和开发至关重要。
