Rough contact is not always bad for interfacial energy coupling
2013
Nanoscale
For the first time we report that by introducing sub-nm roughness on a Si surface, the energy coupling between a single layer graphene (SLG) and the Si substrate can be improved substantially. This is contrary to the traditional view that a rough surface contact will weaken the energy coupling, rather than improve it. Periodical grooves of 2 nm width and 2 nm spacing are introduced on the surface of a Si substrate. It is surprisingly found that when the groove depth (d) is less than 0.54 nm,
