- Graphene - Semiconducting and metallic dependence on edge properties.
I have a question concerning the differentiation between the zigzag and armchair pattern of graphene. Specifically concerning the fact that zigzag edges produce metallic properties and armchair edges producing semiconducting/metallic properties.
How does this relate to the orientation of graphene? As in, if I were to measure the conductance across a nanoribbon of graphene and it is oriented such that the armchair patterns are long the sides, is there no way for me to get the semiconducting property? And how does this property dependence change when I look at a nanoribbon with periodic boundary conditions?
