| Sumario: | <p id="p1">The rapid advancement of digital electronics has been driven by the relentless scaling of transistors, as described by Moore’s law. However, as silicon-based technologies approach, their physical limits, alternative materials, and circuit paradigms are being explored to sustain progress. This chapter investigates the potential of graphene nanoribbon field-effect transistors (GNRFETs) and carbon nanotube field-effect transistors (CNTFETs) as next-generation transistor technologies, particularly in the context of ternary logic circuits. Ternary logic offers advantages in information density, computational efficiency, and reduced interconnect complexity. GNRFETs leverage the tunable bandgap and high carrier mobility of graphene nanoribbons, while CNTFETs utilize the exceptional electrical properties of carbon nanotubes, including near-ballistic transport and high electron mobility. Key aspects such as energy efficiency, fabrication scalability, and device performance are analyzed, highlighting the strengths and challenges of each technology. Both technologies face significant challenges, including large-scale fabrication, device variability, and integration with existing silicon-based systems. The study concludes by exploring future prospects, such as hybrid architectures, scalable manufacturing techniques, and advanced applications in neuromorphic computing and optoelectronics. By addressing these challenges, GNRFETs and CNTFETs have the potential to revolutionize digital electronics, enabling faster, more energy-efficient, and compact devices for the next generation of computing systems.</p> |
