Researchers grow graphene on silver

Graphene, a one-atom-thick carbon layer with extraordinary conductivity and strength, holds promise for a range of applications, but to realize its potential scientists must perfect techniques to tune its properties. Growing graphene on silver in ultra-high vacuum could result in an exceptionally pristine sample, presenting opportunities for ultrafast electronics and advanced optics, but current methods for growing graphene on metals have been unsuccessful with silver.

Researchers from Northwestern University and Argonne National Laboratory have recently overcome these limitations, demonstrating the first growth of graphene on a single-crystal silver substrate. Their method could advance graphene-based optical devices and enable the interfacing of graphene with other two-dimensional materials.

The study is published today (Nov. 15) in the journal Nature Communications.
