# Technical Document Extraction: Heatmap Analysis of K₁ and E_F Parameters ## Panel (e): K₁ with E_F = +0.035t - **Axis Labels**: - **X-axis**: `length (nm)` (range: -40 nm to +40 nm) - **Y-axis**: `width (nm)` (range: -10 nm to +10 nm) - **Color Bar**: - **Range**: 0.0 (white) to 0.6 (dark red) - **Label**: Intensity scale (no explicit units) - **Key Observations**: - **Red Intensity**: Concentrated on the right side of the plot (length > 20 nm). - **Gradient**: Smooth transition from white (low intensity) to red (high intensity). - **Symmetry**: Mirror-like pattern across the width axis (y = 0 nm). ## Panel (g): K₁ with E_F = -0.035t - **Axis Labels**: - **X-axis**: `length (nm)` (range: -40 nm to +40 nm) - **Y-axis**: `width (nm)` (range: -10 nm to +10 nm) - **Color Bar**: - **Range**: 0.0 (white) to 0.6 (dark red) - **Label**: Intensity scale (no explicit units) - **Key Observations**: - **Red Intensity**: Distributed across the entire plot with localized peaks near the edges (length ≈ ±40 nm). - **Wave-like Patterns**: Oscillatory intensity variations along the length axis. - **Asymmetry**: No mirror symmetry; intensity peaks are offset relative to the width axis. ## Cross-Referenced Legend Consistency - **Color Bar Alignment**: - Both panels use identical color scales (0.0–0.6), ensuring consistent intensity interpretation. - Red regions in both panels correspond to values ≥ 0.4, as per the color bar. ## Summary of Trends 1. **Positive E_F (+0.035t)**: - High-intensity regions are spatially confined to the right half of the plot. - Suggests directional dependence of K₁ under positive E_F. 2. **Negative E_F (-0.035t)**: - Intensity variations are more distributed, with edge-localized peaks. - Indicates a different spatial modulation of K₁ under negative E_F. ## Diagram Components - **Arrows**: Black arrows on the x-axis indicate the direction of increasing length. - **Heatmap Grid**: Overlaid red/yellow lines represent intensity gradients. - **Panel Titles**: Explicitly label the parameter conditions (K₁ and E_F values). ## Data Extraction Notes - No explicit numerical data table is present; values are inferred from color intensity. - Critical parameters: K₁ (dependent variable), E_F (independent variable with ±0.035t values).
