In the cutting-edge field of nanotechnology, where the pursuit of ultimate performance is paramount, the intrinsic quality of materials serves as the cornerstone that determines the upper limit of device capabilities. In the realm of nanomaterials, single-walled carbon nanotubes (SWCNTs) are hailed as the "ultimate nanomaterial" due to their unique one-dimensional tubular structure and exceptional electrical, mechanical, and thermal properties. The arc-discharge method is a critical pathway to translate this theoretical potential into reality. The arc-discharge single-walled carbon nanotubes optimized and provided by the research team of Associate Researcher Yanjie Su from Shanghai Jiao Tong University represent an outstanding achievement along this path, specifically designed for foundational and applied research that demands extreme performance.
I. The Arc-Discharge Method: The Art of Fabrication Defining "Structural Perfection"
The arc-discharge method is not a novel technique, yet it remains an irreplaceable classic process for producing single-walled carbon nanotubes of the highest intrinsic quality. Its core advantage stems from the high-temperature plasma growth environment:
-
Extreme Crystallinity, Minimal Defects: The high temperature promotes nearly perfect sp² hybridized carbon atom arrangement, resulting in an exceptionally high degree of graphitization and extremely low structural defect levels. This is the fundamental basis for achieving superior electrical properties.
-
Pure Single-Walled Structure: The process ensures the product is 100% single-walled carbon nanotubes, effectively avoiding interference from by-products such as multi-walled nanotubes and carbon nanoparticles. This provides a pure and homogeneous material system for research.
-
Exceptional Intrinsic Electrical Properties: The extremely low defect density directly translates into remarkably high carrier mobility, making it an ideal "electronic highway" for constructing high-speed, high-efficiency electronic and optoelectronic devices.
