Electromagnetic-Semiconductor Coupled Solver in Multsicale Simualtions

By using the (electric) scalar potential and (magnetic) vector potential as fundamental variables, we rewrite the original Maxwell's equations, and couple the drift-diffusion equation for semiconductors. In order to balance the accuracy and efficiency, we can further combine the quantum mechanics and newly developed electromagnetic-semiconductor coupled solver to study emerging optoelectronic materials. Our multiscale simulation methods are indispensable components of next generation modeling tools for the material design.
