Graphene, a two-dimensional material with unique electronic properties, has recently gained significant attention in the field of electronics. However, despite its potential applications, many people wonder why graphene nanoribbons (GNRs) differ significantly from traditional sheets of graphene.
(why is graphene nanoribbon electronically different from a sheet of graphene?)
One key factor that sets apart GNRs from sheets of graphene is their thickness. GNRs can have a width much thinner than a typical sheet of graphene, making them ideal for use in electronic devices where space and weight are critical considerations. This thinness also allows for greater flexibility and modularity in design, as the thickness can be easily adjusted to suit specific needs.
Another important aspect of GNRs is their electronic conductivity. While sheets of graphene are known to have high electrical conductivity, GNRs possess a much lower value due to the presence of more conducting atoms along the ribbon’s edges. This property makes GNRs an attractive candidate for use in transistors and other electronic components, where low electrical resistance is desired.
Additionally, GNRs exhibit unique mechanical properties that make them useful in various applications. For example, GNRs can be easily manipulated using chemical or physical means, which makes them ideal for use in flexible electronics and. Furthermore, the zero bandgap nature of GNRs makes them suitable for use in energy storage systems, where the ability to store energy in a narrow range of frequencies is essential.

In conclusion, while graphene sheets are widely used in electronics due to their unique electronic properties, GNRs offer additional advantages such as their smaller thickness, higher electronic conductivity, unique mechanical properties, and suitability for various applications. As research continues to advance in this field, it is likely that GNRs will play an increasingly important role in shaping the future of electronics.
