Electronic properties of graphene - Wikipedia

Electrical resistance in 40-nanometer-wide nanoribbons of epitaxial graphene changes in discrete steps. The ribbons' conductance exceeds predictions by a factor of 10. The ribbons can act more like optical waveguides or quantum dots, allowing electrons to flow smoothly along the ribbon edges. In copper, resistance increases in proportion to length as electrons encounter impurities.

Electromagnetic interference shielding with graphene

Sep 28, 2020 · It was found that the composites of 1 mm thickness with graphene loading of only 8 wt% provide excellent electromagnetic shielding of 70 dB in the sub-terahertz EHF frequency with negligible energy reflection to the environment (Figure 1 and 2). The 70-dB shielding corresponds to blocking 99.99999% of EM energy.
