Nanowire devices have attracted considerable attention because of their unique structure and novel properties, and have opened up significant development opportunities. However, not many studies have focused on their stability and durability under practical conditions, which limits the rapid development of real applications. Herein, we systematically investigate three different treatments,polymer coating, inert atmosphere protection, and thickness-induced self-protection, to protect the tellurium nanowire devices from oxidation when exposed to open air. The degree of oxidation was monitored by examining changes in the valence states of tellurium element and in the morphology of the nanowires. After the protective treatments, the tellurium nanowire devices showed improved stability and remained stable even after 800 days of storage. This work highlights the importance of investigating the stability of nanowire devices, especially for their practical applications.

空气中纳米线装置的稳定性和保护

纳米线器件由于其独特的结构和新颖的性能而吸引了相当多的关注，并开辟了巨大的发展机会。但是，很少有研究关注其在实际条件下的稳定性和耐用性，这限制了实际应用的快速发展。在本文中，我们系统地研究了三种不同的处理方法，即聚合物涂层，惰性气氛保护和厚度诱导的自我保护，以保护碲纳米线器件在暴露于露天时不被氧化。通过检查碲元素的价态变化和纳米线的形态来监测氧化程度。经过保护性处理后，碲纳米线器件显示出更高的稳定性，即使在存储800天后仍保持稳定。
