Electronic Structure of Ribbons

In summary, the conversation discusses the calculation of band structure of 2D sheets using the tight binding method. The speaker is seeking a reference to learn how to calculate the band structure of 2D ribbons, such as Graphene nanoribbon and Silicene nanoribbon, using the same method. The conversation also suggests considering the size and edge type of the nanoribbon, and potentially using DFT code for easier calculations. A comprehensive tutorial on obtaining electronic structures through analytical methods is recommended as a helpful resource.

I know how to calculate band structure of two dimensionaI sheets by tight binding. I am looking for a reference to learn thoroughly how to calculate band structure of 2d-ribbons (Graphene nanoribbon, Silicene nanoribbon,...) using tight binding method. Could anyone please help me?

When calculating the band structure of graphene you assume it's infinite in extent through the Bloch Theorem. Decide how wide you want the nanoribbon to be and whether you want armchair or zigzag edges. It may be easier to work out some DFT code.
