Role of Graphene in Improving Thermal Dissipation and Electrical Performance

EasyChair Preprint 14487

Abstract

Graphene, a single layer of carbon atoms arranged in a two-dimensional honeycomb lattice, has garnered significant attention due to its remarkable thermal and electrical properties. Its high thermal conductivity, approximately 5000 W/m·K, enables effective heat dissipation, making it an ideal material for enhancing thermal management in electronic devices. Graphene's ability to conduct heat efficiently is leveraged in various applications, including heat spreaders, thermal interface materials, and composites, improving the performance and reliability of electronics such as processors and LEDs.

In addition to its thermal benefits, graphene exhibits extraordinary electrical conductivity with electron mobility reaching up to 200,000 cm²/V·s. This exceptional conductivity is due to the material's delocalized π-electrons and minimal scattering, which significantly enhances the performance of electronic components. Graphene is employed in conductive inks, transistors, supercapacitors, and batteries, driving advancements in flexible electronics, high-speed transistors, and energy storage technologies.

Keyphrases: Graphene, High-Speed Transistors, electrical conductivity, flexible electronics, thermal conductivity
