Abstract The in situ manipulation and property investigation of individual one-dimensional (1-D) nanomaterials (such as nanowires, nanotubes and 1-D heterostructures) as well as the construction of nanodevices based on these nanomaterials that have potential vital applications have become the focus of researchers worldwide. In recent years, the studies on these nanostructures have mainly shifted to three aspects of in-situ manipulation, property investigation and application exploration. The high-resolution transmission electron microscope (HRTEM) equipped with an atomic force microscope (AFM) or a scanning tunneling microscope (STM) holder, and a heating/cooling holder has already developed as the most advanced technology capable of implementing in situ manipulation on and probing physical properties of nano-objects. In this review, we will summarize the significant developments in regards to the on-demand manipulation, thermal, mechanical, and electrical property investigations of 1-D nanomaterials as well as exploring their applications in piezoelectrical devices, lithium ion batteries and field emission devices. The highlight here is that inside a transmission electron microscope (TEM), the thermal, mechanical and electrical transport data are acquired in real time with three-dimensional (3-D) manipulation on one particular nano-object and can thus reflect the dynamic morphological, structural and chemical changes of a given nanomaterial.

一维纳米材料的原位透射电子显微镜研究:操作、性质和应用

摘要 单个一维 (1-D) 纳米材料(如纳米线、纳米管和一维异质结构)的原位操作和性能研究以及基于这些具有潜在重要应用的纳米材料的纳米器件的构建已成为全世界研究人员的关注点。近年来,对这些纳米结构的研究主要转向原位操纵、性质研究和应用探索三个方面。配备原子力显微镜 (AFM) 或扫描隧道显微镜 (STM) 支架和加热/冷却支架的高分辨率透射电子显微镜 (HRTEM) 已经发展成为能够实现原位操作的最先进技术和探测纳米物体的物理特性。在这次审查中,我们将总结一维纳米材料在按需操纵、热、机械和电性能研究方面的重大进展,并探索它们在压电器件、锂离子电池和场发射器件中的应用。这里的亮点是在透射电子显微镜 (TEM) 内,通过对一个特定纳米物体的三维 (3-D) 操作实时获取热、机械和电传输数据,因此可以反映动态形态,给定纳米材料的结构和化学变化。锂离子电池和场发射装置。这里的亮点是在透射电子显微镜 (TEM) 内,通过对一个特定纳米物体的三维 (3-D) 操作实时获取热、机械和电传输数据,因此可以反映动态形态,给定纳米材料的结构和化学变化。锂离子电池和场发射装置。这里的亮点是在透射电子显微镜 (TEM) 内,通过对一个特定纳米物体的三维 (3-D) 操作实时获取热、机械和电传输数据,因此可以反映动态形态,给定纳米材料的结构和化学变化。
