By employing AC-STMBJ with a bis(thioanisolyl)butadiynyl probe, we resolve sub-millisecond transients across eight organic solvents, categorised by their dielectric response: - Group A: Non-polar (e.g. Mesitylene, Decane) -> Resistive response. - Group B: Intermediate (e.g. Anisole, TCB) -> Quasi-linear capacitive response. - Group C: Highly Polar (e.g. GBL, PC) -> Non-linear/Asymmetric dynamics. ============================================================================================================== DIRECTORY STRUCTURE ============================================================================================================== 📁 01_raw_data ├── 📂 data_1k_50Hz <-- Core dataset at 50Hz (anisole, decane, gbl, etc.) └── 📂 data_1k_100Hz <-- High-frequency verification set (anisole) 📁 02_postprocessing ├── 🛠️ nanoedl_unified_analysis.py <-- Extracts Rm, Rs, Ceq & analyses Group C transients ├── 🛠️ nanoedl_2d_histogram_logg_vs_time.py <-- Conductance vs Displacement/Time 2D mapping └── 📂 processed <-- Crunched raw data files for processinf ============================================================================================================== TECHNICAL SPECIFICATIONS ============================================================================================================== - INSTRUMENTATION: Modified STMBJ (Liverpool Lab) - SAMPLING RATE: 40 kHz - EXCITATION: Square-wave, 2V peak-to-peak (or 0.2 V peak-to-peak if specified) - TIP WITHDRAWAL: 10 nm/s - TEMPERATURE: 298 K (ambient) ============================================================================================================== CITATION & LICENCE ============================================================================================================== If you use this data or code, please cite: Listo, R., et al.
