Band Gap of Atomically Precise Graphene Nanoribbons as a Function of Ribbon Length and Termination

Leopold Talirz, Hajo Söde, Shigeki Kawai +7

We study the band gap of finite $N_A=7$ armchair graphene nanoribbons (7-AGNRs) on Au(111) through scanning tunneling microscopy/spectroscopy combined with density functional theor…
