Kagome Graphene with Promising Properties
Researchers from the Department of Physics and the Swiss Nanoscience Institute at the University of Basel, working in collaboration with the University of Bern, have produced and studied Kagome graphene for the first time. Their report in the journal Angewandte Chemie shows the synthesis of a nitrogen-doped Kagome graphene using a surface-assisted Ullmann coupling on Ag(111).
The Kagome graphene, made of carbon and nitrogen atoms, forms a regular lattice of hexagons and triangles. The researchers' measurements of the Kagome graphene have delivered promising results that point to unusual electrical or magnetic properties. These properties show promise for future potential applications including electronic sensors, quantum computers, and efficient electronic components.
Researchers employed scanning tunnelling and atomic force microscopes (STM/AFM), including a Low Temperature Scanning Tunnelling Microscopy (LT STM), to explore the structural and electronic properties of the Kagome graphene down to the atomic scale. Their research demonstrated its semiconducting character due to the nitrogen doping as well as the emergence of Kagome flat bands near the Fermi level.
We at Scienta Omicron look forward to following the further investigations into this exciting area from the research teams at the University of Bern and the University of Basel.
