摘要

在热处理过程中,同时采用原位薄片电阻和x射线衍射测量来研究Ti电极与Ge-Te相变材料的接触。发现Ti与GeTe反应生成TiTe2和Ge。经过400℃热处理后,原子探针层析分析证实了这两相的存在。

Stability of GeTe-based phase change material stack under thermal stress: Reaction with Ti studied by combined in-situ x-ray diffraction, sheet resistance and atom probe tomography
In situ sheet resistance and x-ray diffraction measurements were used simultaneously during heat treatment to study Ti electrodes in contact with Ge-Te phase change materials. Ti is found to react with GeTe forming TiTe2 and Ge. Atom probe tomography analyses confirm the presence of these two phases after a 400°C heat treatment.
