# Technical Document Extraction: Heatmap Analysis of WS2 Samples
## Panel (k) - WS2: E_F = -300 (meV), θ = 15°
- **Title**: `(k) WS2: E_F=-300 (meV), θ=15°`
- **Axes**:
- **X-axis**: `length (nm)` (range: -40 to 40 nm)
- **Y-axis**: `width (nm)` (range: -10 to 10 nm)
- **Color Scale**:
- **Range**: 0 to 10 (units unspecified)
- **Gradient**: White (low) → Red (high)
- **Key Observations**:
- Symmetric intensity distribution centered at (0, 0).
- Red ring-like structure with uniform intensity (~10 max).
- No significant spatial variation within the ring.
## Panel (l) - WS2: E_F = -300 (meV), θ = 15°
- **Title**: `(l) WS2: E_F=-300 (meV), θ=15°`
- **Axes**:
- **X-axis**: `length (nm)` (range: -40 to 40 nm)
- **Y-axis**: `width (nm)` (range: -10 to 10 nm)
- **Color Scale**:
- **Range**: 0 to 15 (units unspecified)
- **Gradient**: White (low) → Blue (high)
- **Key Observations**:
- Asymmetric intensity distribution with a blue core (~15 max) and red peripheral ring.
- Core intensity localized near (0, 0), with peripheral ring extending to ~±20 nm in length.
- Higher maximum intensity (15) compared to Panel (k).
## Cross-Reference: Color Legend Consistency
- **Panel (k)**: Red corresponds to highest intensity (10).
- **Panel (l)**: Blue corresponds to highest intensity (15).
- **Angle Consistency**: Both panels share identical θ = 15° parameter.
## Structural Notes
- Both panels represent the same material (WS2) and Fermi energy (E_F = -300 meV).
- Divergent intensity profiles suggest differences in experimental conditions or material properties between (k) and (l).
