Abstract

Flexible information memory played a key role in flexible electronic devices and smart wearables. This paper was focused on the effect of flexible deformation on the properties of (MoTe₂)_xSb_1-x nano-phase-change films based on PEEK substrates. By placing the films at the finger, wrist, back of the hand and elbow and bending them, the resistance values showed periodic fluctuations with bending but the changes were not significant. After 100,000 bending cycles and 4,000 s of vibration, the films successfully achieved the transformation from a shapeless to a structured state. The stress caused by bending and vibration affects the surface roughness of the flexible film and weakens the adhesion between the film and the substrate. Flexible (MoTe₂)_0.07Sb_0.93 film electronics were prepared, and the phase change memory devices could realize reversible transitions between SET and RESET states with 100 ns pulse widths in the flat state, after 100,000 bending cycles, and after 4,000 s of vibration. These findings indicated that (MoTe₂)_0.07Sb_0.93 films based on flexible PEEK substrates had promising applications in the field of flexible phase change memory.

基于柔性 PEEK 基底的 (MoTe2)xSb1-x 薄膜的相变行为

柔性信息存储器在柔性电子设备和智能可穿戴设备中发挥着关键作用。本文主要研究了柔性形变对基于 PEEK 基底的 (MoTe2)xSb1-x 纳米相变薄膜性能的影响。将薄膜置于手指、手腕、手背和肘部并弯曲，电阻值随弯曲呈现周期性波动，但变化不大。经过 100,000 次弯曲和 4,000 秒振动后，薄膜成功实现了从无形到结构化的转变。弯曲和振动产生的应力影响了柔性薄膜的表面粗糙度，削弱了薄膜与基底之间的粘附力。制备出的柔性（MoTe2）0.07Sb0.93 薄膜电子器件在平坦状态、100,000 次弯曲周期和 4,000 秒振动后，都能实现 SET 和 RESET 状态之间 100 ns 脉宽的可逆转换。这些研究结果表明，基于柔性 PEEK 基底的 (MoTe2)0.07Sb0.93 薄膜在柔性相变存储器领域具有广阔的应用前景。
