Particle-level charge carrier visualization makes semiconductor physics actually visible.

Strengths

•Simulates drift and diffusion currents simultaneously with distinct visual markers for electrons and holes.
•Desktop software extends beyond basics to model IGBTs and SCRs with similar fidelity.
•Recombination events rendered as white flashes provide intuitive feedback on carrier dynamics.

Weaknesses

•Animations are static exports; interactive simulation requires downloading separate desktop software.
•No quantitative data overlay on the web animations, limiting utility for precise analysis.

Post Description

Hi HN, I made some animations of the most important kinds of transistors using my semiconductor simulation, details of which are on the page. I tried to make the visuals as realistic as possible while also aiming for clarity. If you want to go beyond the charge carriers and look at, for example, the electric field, you can do so in the simulation software. The desktop software also has less common devices like IBGTs and SCRs that have similar animations.
