Physicists use selenium doping to achieve high selectivity in nanostructures
Scanning tunneling microscope image of the reaction pathway of mTBPT on a Cu(111) substrate, showing the transition from a random metal-organic structure before selenium doping to a well-ordered, crystalline, two-dimensional metal-organic nanostructure after doping. Credit: Nature Communications (2024). DOI: 10.1038/s41467-024-47614-9 Physicists at the National University of Singapore (NUS) have used flexible precursors and selenium doping to achieve controlled conformations of…
