论文摘要
即将到来的用于可折叠显示器的灵活的超薄玻璃吸引了广泛的关注，作为刚性电子智能手机的替代方法。但是，尚不清楚玻璃化学加强的详细组成效应。空间分辨的化学和钢化玻璃压缩层的深度远非清晰。在这项研究中，使用常用的X射线光谱技术和原子探针断层扫描（APT）相对研究，以研究两种代表性智能手机玻璃样品中组成元件的分布：非脾气和化学的玻璃。使用APT，分析可能影响钢玻璃故障的碱（Li，Na，K，Ca）在亚纳米级分辨率下是可行的。证明APT可以被视为用于移动应用中玻璃化学分布的替代技术。
The upcoming flexible ultra-thin glass for foldable displays has attracted widespread attention as an alternative to rigid electronic smartphones. However, the detailed compositional effect of the chemical strengthening of the glass is not well understood. The spatially resolved chemistry and the depth of compression layer of tempered glass is far from being clear. In this study, commonly-used X-ray spectroscopy techniques and atom probe tomography (APT) were used comparatively to investigate the distribution of constituent elements in two representative smartphone glass samples: non-tempered and chemically-tempered glasses. Using APT, analysing the alkalis (Li, Na, K, Ca) that could impact the failure of the tempered glass was feasible at sub-nanoscale resolution; demonstrating that APT can be regarded as an alternative technique for imaging chemical distribution in glass for mobile applications.
