Data Transmission Performance of Few-Layer Graphene Ribbons

摘要

We investigated the electrical characteristics and digital data transmission performance few-layer graphene ribbons grown by chemical vapor deposition. Graphene ribbons having a mobility of 2,180 cm~2V~(-1)s~(-1) can sustain data rates up to 50 megabits per second at 1.5 urn length, thus the bandwidth is inversely proportional to resistance caused by defects in the graphene layers. Improving the graphene mobility to highest measured values (-200,000 cm~2V~(-1)s~(-1)) and using structures with multiple coplanar transmission lines in parallel could carry the bandwidth beyond the gigabits per second level.
