A group of scientists at Nagoya University, Japan, have developed a simple method to construct perfectly unidirectional molecular structures on graphene surfaces. They published their findings in Scientific Reports.
 
Graphene, which are sheets made out of carbon, is attracting interest as a powerful candidate material for manufacturing next-generation electronics. The development of a reliable method that enables the perfect alignment of molecules or molecular assemblies on a graphene surface may allow the fine-tuning of the electric properties of graphene, thereby improving the performance of graphene-based electronic devices.
 
Although widely studied in recent years, the growth of well-aligned molecular nanostructures along a specific axis has proven to be difficult. This is because the graphene surface has three-fold symmetry, thus making it difficult to align the molecules in a particular direction.
 
To resolve this problem, a team led by Dr. Yuhei Miyauchi and Professor Kenichiro Itami of the JST-ERATO Itami Molecular Nanocarbon Project and the Institute of Transformative Bio-Molecules (ITbM) focused on the physical changes induced by atomic force microscopy (AFM) tip scanning.
