# Technical Data Extraction: MoSe2 Current Density and Streamline Analysis
This document provides a detailed technical extraction of the data presented in the provided image, which consists of two side-by-side heatmaps with overlaid streamlines, labeled (g) and (h).
## 1. General Metadata
* **Subject Matter:** Physics/Materials Science simulation of Molybdenum Diselenide (MoSe2).
* **Parameters (Common to both):**
* **Fermi Energy ($E_F$):** -95 (meV)
* **Twist Angle ($\theta$):** 15°
* **Coordinate System:**
* **X-axis:** length (nm), ranging from -40 to 40.
* **Y-axis:** width (nm), ranging from approximately -15 to 15 (ticks at -10, 0, 10).

## 2. Component Analysis: Plot (g)
### Header Information
* **Label:** (g)
* **Title:** MoSe2: $E_F$=-95 (meV), $\theta$=15°
### Spatial Data & Trends
* **Region Isolation:** The data is heavily concentrated on the left side of the plot (length -40 nm to -20 nm). The rest of the plot (length -20 nm to 40 nm) is white/null, indicating zero or negligible magnitude.
* **Heatmap (Magnitude):**
* **Color Scale:** Located at the right of the plot. A gradient from white (0.0) to dark red (~0.45).
* **Peak Intensity:** Reaches values > 0.4 near the left boundary (length = -40 nm) at widths of approximately ±10 nm.
* **Streamlines (Flow):**
* **Visual Trend:** Red streamlines originate from the left boundary. They curve inward toward the center (width = 0) and then dissipate as they move toward length = -20 nm.
* **Directionality:** The arrows indicate flow moving from the left edge toward the center-right of the localized active zone.

## 3. Component Analysis: Plot (h)
### Header Information
* **Label:** (h)
* **Title:** MoSe2: $E_F$=-95 (meV), $\theta$=15°
### Spatial Data & Trends
* **Region Isolation:** Unlike plot (g), data is distributed across the entire length (-40 nm to 40 nm).
* **Heatmap (Magnitude):**
* **Color Scale:** Located at the right of the plot. A gradient from white (0.0) to dark red (~0.35). Note the maximum scale is lower than in plot (g).
* **Pattern:** Shows a periodic or "wavy" distribution of intensity. Higher magnitudes (light orange/brown) are seen in horizontal bands near width ±10 nm.
* **Streamlines (Flow):**
* **Visual Trend:** Blue streamlines dominate this plot. They exhibit a complex, oscillatory flow pattern across the entire length.
* **Vortices/Features:** There are two distinct "eye" or depletion regions (white areas) centered at approximately:
1. Length ≈ -15 nm, Width ≈ 0 nm
2. Length ≈ 15 nm, Width ≈ 0 nm
* **Flow Path:** The streamlines flow around these central white regions, creating a wave-like motion that propagates from left to right across the channel.
