Carbon Nanotube and Graphene Nanoribbon Interconnects

This book presents a detailed analysis and modeling of carbon nanotube and graphene nanoribbon interconnects. It first discusses the theory and basics of both carbon nanotube and graphene nanoribbon. Depending on their structure, they can exhibit either metallic or semiconducting properties. Due to the excellent current-carrying capability and long mean free path, these materials find suitability as future interconnects. The book then presents the details of electrical circuit model for both carbon nanotube and graphene nanoribbon.

An Alternative to Copper-Based Interconnect Technology

With an increase in demand for more circuit components on a single chip, there is a growing need for nanoelectronic devices and their interconnects (a physical connecting medium made of thin metal films between several electrical nodes in a semiconducting chip that transmit signals from one point to another without any distortion). Carbon Nanotube and Graphene Nanoribbon Interconnects explores two new important carbon nanomaterials, carbon nanotube (CNT) and graphene nanoribbon (GNR), and compares them with that of copper-based interconnects. These nanomaterials show almost 1,000 times more current-carrying capacity and significantly higher mean free path than copper. Due to their remarkable properties, CNT and GNR could soon replace traditional copper interconnects. Dedicated to proving their benefits, this book covers the basic theory of CNT and GNR, and provides a comprehensive analysis of the CNT- and GNR-based VLSI interconnects at nanometric dimensions.

The book starts off with a brief introduction of carbon nanomaterials, discusses the latest research, and details the modeling and analysis of CNT and GNR interconnects. It also describes the electrical, thermal, and mechanical properties, and structural behavior of these materials. In addition, it chronicles the progression of these fundamental properties, explores possible engineering applications and growth technologies, and considers applications for CNT and GNR apart from their use in VLSI circuits.

Comprising eight chapters this text:

• Covers the basics of carbon nanotube and graphene nanoribbon
