Graphene Nanoribbons Could Bring About the Next Generation of Tiny Electronics

Graphene nanoribbons, with their tiny size and highly advanced electricity conductivity properties, are seen as the best hope to replace existing semiconductor technology. So-called large-scale integrated circuits (LSIs) using semiconductors can be found in a wide variety of electronics ranging from smartphones to home computers. LSIs have enabled electronics makers to shrink down the size of their devices over the years without sacrificing performance, but the ability to miniaturize them while remaining effective might be close to its limit.

“Silicon semiconductors are giving us better performance at smaller sizes. However, we are reaching the limit in how small we can make devices. Thus, we have high expectations for the performance of graphene nanoribbons, which have semi-conducting properties that are only one atom thick – a 2D material,” notes Dr. Shintaro Sato of Fujitsu Ltd.

Fujitsu Ltd, Nara Institute of Science and Technology, and University of Tokyo recently reported in a new collaborative study the first-ever 17-carbon wide graphene nanoribbon with the smallest bandgap ever seen in a nanoribbon created from bottom-up or “on-surface synthesis.”

Created at a commercial scale, the team hopes these graphene nanoribbons could pick up where LSI-based semiconductors left off, allowing even smaller, more powerful consumer electronics.
