Characteristics and Improvement Methods of Carbon Nanodevices

Whether the trend of increasing integration density of integrated circuits indicated by Moore's Law can continue to develop, especially now that feature sizes have entered the nanometer range, shrinking sizes face greater challenges. Since entering the "post-Moore" era, the development of carbon-based nanoelectronics has attracted attention. This paper explores the application of carbon-based nanomaterials in carbon-based nanoelectronic devices and integrated circuits. It introduces the structure, properties, and preparation methods of single-walled carbon nanotubes and graphene, demonstrating their importance to carbon-based nanoelectronic devices and integrated circuits. The synthesis methods of carbon nanotubes mainly include arc discharge method, laser ablation method, and chemical vapor deposition metho. Subsequently, it summarizes the advantages, applications, and challenges of carbon-based nanoelectronic devices. The applications of carbon-based nanoelectronic devices and integrated circuits include digital integrated circuits, optoelectronic integrated circuits, electrochemical sensors, carbon-based radio frequency devices, and smart integrated systems. Furthermore, starting from the preparation methods, improvement methods are summarized, focusing on chemical vapor deposition, to optimize carbon nanomaterials for application in carbon nanodevices. It elucidates the promising prospects of carbon-based nanoelectronics.
