Abstract

Two-dimensional (2D) transition metal carbides and nitrides, referred to as MXenes, are attracting increasing attention as adaptable components for high-performance electrical and sensing devices. This perspective examines their function across three intersecting platforms: resistive switching memory, gas sensors, and gasistors that integrate both functionalities. Solution-based synthesis, laser patterning, and low-temperature assembly on flexible substrates are emphasized as methods that accelerate the transition from powder to device. Spontaneous oxidation, moisture-driven degradation, and precise termination control remain challenges to overcome, but new solutions, including surface passivation, fluoride-free etching, and data-driven material selection, are being developed rapidly. This article proposes design guidelines that connect atomic-scale chemistry with device-level metrics, facilitating the transition of MXene memories, sensors, and gasistors from proof-of-concept studies to reliable systems for energy storage, neuromorphic computation, and environmental monitoring.

二维MXenes驱动多功能电阻存储器，气体传感，和气敏器件：一个视角

二维（2D）过渡金属碳化物和氮化物，称为MXenes，作为高性能电气和传感设备的适应性组件，正引起越来越多的关注。本文从三个交叉平台的角度分析了它们的功能：电阻开关存储器、气体传感器和集成这两种功能的气阻器。基于溶液的合成、激光图像化和柔性基板上的低温组装被强调为加速从粉末到器件过渡的方法。自发氧化、水分驱动降解和精确终止控制仍然是需要克服的挑战，但新的解决方案，包括表面钝化、无氟蚀刻和数据驱动的材料选择，正在迅速发展。本文提出了将原子尺度化学与设备级指标联系起来的设计指南，促进了MXene存储器、传感器和气瓶从概念验证研究到可靠的能量存储、神经形态计算和环境监测系统的过渡。图形抽象
