# 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
