Generally speaking, graphene nanoribbons today are synthesized on gold surfaces that act as a catalyst for their formation, but gold is expensive and a conductor of electricity, ...

Graphene Nanoribbons might soon be much easier to produce. An international research team led by Martin Luther University Halle-Wittenberg (MLU), the University of Tennessee and Oak Ridge National ...

Graphene nanoribbons measure only several nanometers across, beyond the limits of conventional chip top-down patterning used in chip manufacturing. As a result, when carved from larger pieces of ...

MADISON, Wis. -- Graphene, an atom-thick material with extraordinary properties, is a promising candidate for the next generation of dramatically faster, more energy-efficient electronics. However ...

In contrast to graphene, these graphene nanoribbons have a unique electronic structure including a non-zero band gap, which makes them promising candidates for semiconductor applications.

Graphene nanoribbons are narrow sheets of carbon atoms only one layer thick. Their width, and the angles at which the edges are cut, produce a variety of electronic states, ...

Graphene nanoribbons can now easily be grown in laboratories, which could herald a new generation of faster electronic devices. The ribbons are grown on a base of germanium, and the fine fibers ...

Graphene nanoribbons are usually semiconductors, but the team has managed to turn them into metals, which makes them conductive and able to act like wires to carry electrons around a circuit.

According to theoretical studies, narrow graphene nanoribbons with atomically precise armchair edges and widths of <2 nm have a bandgap comparable to that in silicon (1.1 eV), which makes them ...
