Built on the finite element drift-diffusion method, CHARGE provides designers with the correct tools for comprehensive charge transport simulation in active photonic and optoelectronic semiconductor devices. CHARGE self-consistently solves the system of equations describing electrostatic potential (Poisson’s equations) and density of free carriers (drift-diffusion equations). Automatic and guided mesh refinement tools are provided to achieve accuracy while minimizing computational effort.
Key CHARGE applications include:
- Photovoltaic devices
- Image sensors
- Avalanche photodiodes
- Electro-optic modulators
- Semiconductor devices
