| description | •Suspended graphene can reduce scattering effectively.•Fabrication of suspended graphene arrays by silver liquid dynamics.•Suspended graphene improves detection sensitivity for nitrogen dioxide.
Graphene, with excellent electrical and thermal properties, is far from its theoretical limit because of substrate scattering which can be improved by suspending the graphene. Presently, the suspended graphene is generally fabricated by etching, which requires complicated operation. Here, we propose a strategy to prepare suspended graphene arrays by using the surface motion of molten silver. The prepared suspended graphene arrays exhibit stable contact and low contact resistance with electrodes. A gas sensor is demonstrated by using the suspended graphene, which shows high performance in detecting harmful gas nitrogen dioxide. |
