Optical Signatures of Strain Differences in Epitaxial Graphene Nanoribbons
Heather M. Hill, Ching-Chen Yeh, Swapnil M. Mhatre +6
We demonstrate the preparation of both armchair and zigzag epitaxial graphene nanoribbons (GNRs) on 4H-SiC using a polymer-assisted, sublimation growth method. Historically, the pr…
