State diagram showing material classification based on band structure and resulting electrical properties
The map in words
- Classification → Insulator (Large Gap)
- Classification → Conductor (Overlapping Bands)
- Classification → Semiconductor (Small Gap)
- Insulator → Props1 (High Resistivity)
- Conductor → Props2 (Low Resistivity)
- Semiconductor → Props3 (Medium Resistivity)
- Props3 → Behavior (Negative T Coefficient)
