Help & Instructions

New Dynamic Features:

Filled states now fluctuate based on temperature
Animation speed control for different viewing modes
Thermal fluctuation intensity control
Thermal carriers (e⁻/h⁺) appear at high temperatures
Real-time dynamic visualization

How to use:

Select different semiconductor materials
Adjust temperature to see thermal effects
Change doping concentration and type
Control animation speed and thermal effects
Watch dynamic filled states respond to changes

Key Concepts:

Blue curve: Density of States (parabolic)
Red line: Fermi Level position
Green area: Dynamic occupied states
Orange bands: Valence and conduction bands
Moving dots: Thermal carriers (e⁻ = electrons, h⁺ = holes)
