Nanospot Soldering Polystyrene Nanoparticles with an Optical Fiber Probe Laser Irradiating a Metallic AFM Probe Based on the Near-Field Enhancement Effect

In the nanolithography, some exciting developments have been motivated by the tapered metal-coated optical fiber probe irradiated by ultra-fast pulse laser. To explore the related mechanism, the local field is studied using the finite element method in this paper. The simulation results show the reflection at the cut-off plane, edge enhancement effect and surface plasmon resonance become the major factors affecting the near-field. In addition, Based on the near-field distribution and characteristics, the new promising scheme is proposed for near-field nanolithography.

“…For better dispersion effect, the mixed solution was treated with ultrasonic instrument about 2 hours, accompanying the heating operation at approximate 50 C. And aer 10 minutes' standing, supernatant liquid in the centrifuge tube was got as initial sample. [49][50][51] So, according to the above nanospot welding effect under different power and heating time, the laser power and irradiation time were set to 40 mW and 3 minutes respectively. Aer the dispersion treatment of the mixed solution about 1 hour and 10 minutes' standing, the supernatant liquid was also injected with discharge gun, coated on the Si surface with spin coater, and dried with the ow of N 2 , obtaining the nal dispersion sample shown in Fig.…”

The miniaturization of electronic devices into the nanometer scale is indispensable for next-generation semiconductor technology, and carbon nanotubes are considered to be the promising candidates for the future interconnection wires. To study carbon nanotube interconnection during nanowelding, we propose a new nanospot welding method with the near-field enhancement effect of the metallic AFM probe tip irradiated by an optical fiber probe laser. Based on theoretically analyzing the near-field enhancement effect, we set up the experimental system for nanospot welding with good interconnection results of silver nanoparticles and carbon nanotubes, not only proving that the interconnection operation of CNTs can be effectively achieved through the melting process of nanoparticles by the thermal AFM probe tip irradiated by an optical fiber probe laser, but also providing a promising technical approach for nanospot welding.

“…In the near future, CNT arrays can also be used for solar cells, and the photoelectric conversion efficiency can be greatly improved. Meanwhile, a lot of research on controllable joining of CNTs for nano devices requires assembly as a prerequisite . Unfortunately, controllable assembly is still a formidable challenge for us to discover.…”

Carbon nanotubes (CNTs) has been reported for nearly 30 years, but commercial applications is rarely reported. Some reasons for this are related to the CNT properties, especially the electronic properties. Approximately 67% of semiconducting CNTs and 33% of metallic CNTs is usually achieved via a normal synthesis. However, it is difficult to implement a large-scale, ordered assembly of the CNTs. Currently, there are two mainstream methods for obtaining CNTs arrays. Although great progress has been made with direct growth methods using special techniques, there is still room to simultaneously increase both the density and purity. With the development of purification technology, solution assembly methods has attracted tremendous attention because of their ease of processability, low cost of fabrication, and ability to cover large areas at room temperature. In this review, we highlight solution assembly methods and divide the existing methods into three categories. In each category, we give a detailed description of the specific method including the mechanism, an illustration of the process, achievements, advantages, and disadvantages. Finally, the development trends and the research frontier according to our own understanding is described. In this review, a valuable reference for scholars engaged in related research is provided.
