摘要

忆阻器作为新兴的神经形态计算记忆应用的硬件已经显示出前景，但是它们的实际实现受到无序空位缺陷产生的随机导电丝（CF）生长的阻碍。在最近发表在《物质》杂志上的一篇文章中，基于空位有序双钙钛矿Cs2TiBr6纳米晶体开发了一种超快速开关记忆电阻器，在SET和RESET过程中分别实现了28和54 ns的开关时间。有序的空位结构可以预测CF的形成/破裂，从而抑制了迁移的随机性。这些忆阻器的8 × 8横条阵列对去噪图像的识别精度提高了10%，显示了它们在实时视觉信息处理中的潜力。

Vacancy-ordered Cs2TiBr6 memristors: Enabling ultrafast switching and efficient image processing

Memristors have shown promise as hardware for emerging neuromorphic memory-in-computing applications, but their practical implementation is hindered by random conductive filament (CF) growth from disordered vacancy defects. In recent work published in Matter, an ultrafast-switching memristor was developed based on vacancy-ordered double perovskite Cs₂TiBr₆ nanocrystals, achieving switching times of 28 and 54 ns for SET and RESET processes, respectively. The ordered vacancy structure enables predictable CF formation/rupture, which suppresses ion migration randomness. An 8 × 8 crossbar array of these memristors demonstrates 10% improved recognition accuracy for denoised images, showcasing their potential in real-time visual information processing.
