目前用于制备Re-RAMs器件阻变层的材料主要为传统的金属氧化物，动作如NiOx,SiO2,Ta2O5,HfO2,CuOx，动作与此同时新型材料如二维材料，有机-无机杂化钙钛矿材料近年来也被广泛研究。其中，针h种点MAPbI3具有超快阻变速度(200ps)，MAPbCl3器件具有超长保持时间(~7×109s)。
对此，通疫采用氧化铝模包覆隔离的纳米线阵列作为阻变层能有效解决上述问题，在提高器件集成度的同时有效隔绝环境中的空气和水提高阻变层稳定性
它们可以满足狗狗的口腹之欲，苗接还可以提供一些营养。微剪切带作为非均质形核点，个个人个普在半共格界面上形成精细分散的晶内沉淀，形成显著的强度-塑性平衡。
动作研究表明：通过TB滑动的极端剪切变形能力高达364%。针h种点图5机器学习原子间相互作用潜能的开发与评估。
首先通过定向凝固(DS)技术，通疫形成共晶高熵合金，通疫这种合金内部形成了具有仿生鱼骨人字形的，这种结构与梯度结构类似，可以对裂纹的扩展造成多级换缓冲，大大迟缓了材料的过早失效。然而，苗接有序相形成元素的过度合金化可能会导致形成结构上与拓扑封闭填充(TCP)基体不同的相，苗接如σ相、μ相和Laves相，在粗糙的微观尺度上，由于失去了共格性，导致晶界上的不均匀分布。
