FN ISI Export Format VR 1.0 PT J TI Length-dependent symmetry in narrow chevron-like graphene nanoribbons AF Houtsma, R. S. Koen Enache, Mihaela Havenith, Remco W. A. Stöhr, Meike AU Houtsma, RSK Enache, M Havenith, RWA Stöhr, M SO Nanoscale Advances VL 4 BP 3531 EP 3536 PY 2022 AB We report the structural and electronic properties of narrow chevron-like graphene nanoribbons (GNRs), which depending on their length are either mirror or inversion symmetric. Additionally, GNRs of different length can form molecular heterojunctions based on an unusual binding motif. ER
