  • 摘要: 纳米真空隧道结是一种重要的功能元件,(准)弹道输运机制使其具有更低的功耗和理论高达3×108 m/s的传输速度,是实现高性能电子器件的理想选择。利用一维纳米材料制备真空隧道结对于推进器件小型化和高集成具有重要意义。文章利用性质稳定的氧化锌纳米线设计并制备了一维隧道结,研究了其在静电场和超快光激发下的电子发射现象,在超快光场的驱动下实现了六次幂的非线性光发射电流和调制,有望推动一维超快纳米真空电子器件的发展。

     

    Abstract: Nano-vacuum tunneling junction is an important functional component. Its (quasi) ballistic transport mechanism enables it to have lower power consumption and a theoretical transmission speed of up to 3 × 108 m/s, making it an ideal choice for achieving high-performance electronic devices. The preparation of vacuum tunnel junctions using one-dimensional nanomaterials is of great significance in promoting device miniaturization and high integration. This article designs and prepares one-dimensional tunnel junctions using stable zinc oxide nanowires, and investigates their electron emission phenomena under electrostatic field and ultrafast laser excitation. Under the excitation of ultrafast laser, a sixth power high nonlinear emission current and photocurrent modulation have been achieved, which is expected to promote the development of one-dimensional ultrafast nano-vacuum electronic devices.
