Synthesis of zig-zag shape graphene nanoribbons

Article in Nature, Vol. 531, 24 March 2016, pp. 489, “On-surface synthesis of graphene nanoribbons with zigzag edge topology”

 

Summary of article: Using a combination of polymerisation and dehydrogenation, zigzag graphene nanoribbons with bandgaps suitable for spintronics were synthesized and characterized, the latter by scanning tunnelling microscopy and tip functionalized non-contact atomic force microscopy.

 

Comment: In general, the trend in materials science and engineering research has been towards the synthesis of atypical shape nanostructures for exploring unique physical and chemical properties related to memory storage, catalysis, water purification, biological effects etc. To this end, nanostructures of different size and shape have been synthesized using many elements on the periodic table, and their properties shown to be of benefit in both understanding the principles of enhanced performance of materials, as well as allowing new applications to be developed. However, the field remains sparse in knowledge of a unified theme or design principles for endowing specific combinations of elements in particular shapes and structures with unique physicochemical properties.
