Ultrafast electron control⚡️ In our new Nature Communications paper, we switch single-atom charge states in WSe₂ with picosecond THz pulses—capturing atomic-scale ultrafast dynamics. @Empa_CH @PennStateMatSE #QuantumMaterials #Ultrafast #2Dmaterials nature.com/articles/s41467-0…

Ultrafast Coulomb blockade in an atomic-scale quantum dot

Nature Communications - Directly observing ultrafast single electron dynamics at the atomic scale remains a challenge. Here, the authors demonstrate ultrafast Coulomb blockade at selenium vacancies...

📢 We report optimized on-surface synthesis of 17-atom-wide armchair graphene nanoribbons reaching ~17 nm average length. Gradual annealing and high surface coverage enable length enhancement and stability under ambient and harsh conditions. dx.doi.org/10.1021/acsnano.5… @Empa_CH

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...

🔬 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. doi.org/10.1021/acsnano.5c09… @Empa_CH @acsnano

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...

"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.
