A team of researchers has amplified 3D graphene's electrical properties by controlling its curvature.
"Our research showed the conservation and the degradation of the ultra-low dissipative transport of Dirac electrons on the 3D curved surface for the first time," said Yoichi Tanabe, leading author of the study.
Graphene is a 2D atomic-layer material, shaped like honeycombs, which possesses excellent electrical, chemical, thermal, and mechanical properties for a wide range of applications such as semiconductors, electrical batteries, and composites.
Graphene sheets stacked together form graphite which makes up the lead in our pencils. However, packing together graphene tightly means it loses its 2D electronic properties.
One way to overcome this is to separate the graphene sheets with air-f
