# STM Analyzer ## Purpose The STM Analyzer skill provides atomic-resolution surface analysis through scanning tunneling microscopy, enabling visualization of atomic structures and measurement of local electronic properties. ## Capabilities - Atomic-resolution imaging - STS (Scanning Tunneling Spectroscopy) - Local density of states mapping - Surface reconstruction analysis - Molecular imaging - Low-temperature operation protocols ## Usage Guidelines ### STM Analysis 1. **Imaging** - Optimize tunneling parameters - Apply drift correction - Identify atomic features 2. **Spectroscopy** - Acquire dI/dV spectra - Map electronic states - Identify band structure features 3. **Data Processing** - Apply Fourier filtering - Correct for thermal drift - Calibrate atomic distances ## Process Integration - In-Situ Characterization Experiment Design - Structure-Property Correlation Analysis ## Input Schema ```json { "data_file": "string", "analysis_type": "imaging|spectroscopy|sts_mapping", "bias_voltage": "number (V)", "setpoint_current": "number (nA)" } ``` ## Output Schema ```json { "imaging": { "atomic_structure": "string", "lattice_constant": "number (nm)", "defects_identified": ["string"] }, "spectroscopy": { "band_gap": "number (eV)", "fermi_level": "number (eV)", "density_of_states": {"energy": [], "dos": []} } } ```
