Graphene is a two-dimensional material that has unique properties due to its exceptional mechanical strength, electrical conductivity, and thermal stability. One of the most promising applications of graphene is in the field of electronics, particularly as a substitute for silicon-based components.
(what are graphene nanoribbons)
In recent years, scientists have been exploring the possibility of using graphene nanoribbons (GNRs) as electronic devices. GNRs are thin films of graphene that can be applied to electronic components such as transistors and diodes. The advantage of using GNRs as electronic components is that they offer several advantages over traditional semiconductor components. For example, GNRs are highly flexible and can be designed to fit into very small spaces, making them ideal for use in high-tech applications such as aerospace and medical devices.
One of the main challenges in using GNRs as electronic devices is their low electrical conductivity. While this property makes GNRs attractive as a material for use in electronic circuits, it also limits their potential. This is because the high electrical conductivity of GNRs requires the presence of impurities in the film to create conducting channels. However, recent research has shown that it is possible to reduce the amount of impurities in GNRs by using chemical etching techniques. This approach allows for the creation of more conductive GNRs without sacrificing the electrical conductivity of the film.
Another challenge in using GNRs as electronic devices is their high cost. GNRs are expensive to produce due to the need for specialized equipment and materials. However, recent advances in manufacturing technologies have made it possible to reduce the cost of GNRs. For example, researchers have developed new fabrication methods that allow for the production of GNRs at scale on a wide range of substrates. This has made it possible to produce large quantities of GNRs at a lower cost, which could make them more accessible to a wider range of users.

Despite these challenges, GNRs hold great promise for the future of electronics. As researchers continue to explore new ways to use GNRs, it is likely that we will see them used in a variety of applications in the years to come. Whether it is through the development of new electronic devices or the optimization of existing ones, GNRs have the potential to revolutionize the way we interact with technology.
