Optimized Synthesis and Device Integration of Long 17-Atom-Wide Armchair Graphene Nanoribbons
Seventeen-carbon-atom-wide armchair graphene nanoribbons (17-AGNRs) are promising candidates for high-performance electronic devices due to their narrow electronic bandgap. Atomic precision in edge st...

🔬 New in ACS Nano: Triangulene on TbAu₂ shows a strong, spatially modulated interaction with ferromagnetic magnetization (~20 mV Kondo splitting).
➡️ TbAu₂ = new platform for π-magnetic nanographenes.

Proximity-Driven Magnetic Coupling between an Open-Shell Nanographene and a Rare-Earth Surface Alloy
Open-shell nanographenes have attracted significant attention due to their structurally tunable spin ground state. While most characterization has been conducted on weakly interacting substrates such ...

From molecular wires to quantum bits: in our latest work presented in Nature Chemistry, porphyrins are docked to graphene nanoribbons with atomic precision.
Hybrid properties, many possibilities.

"Quantum Lego": We engineered spin-1/2 Heisenberg chains by linking Olympicene nanographenes, unveiling their length-dependent spin excitations. With STM/IETS, we confirm gapless behavior in the thermodynamic limit & visualize spinon standing waves.

In our latest work, we show a sub-exponential increase in charge-state lifetime of Se vacancies in WSe₂, from picoseconds in monolayers to nanoseconds in multilayers. Great collaboration with @pennstatematse.bsky.social !
