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.

The last thread about my software was posted here about a year ago: https://news.ycombinator.com/item?id=43942279

Ohhh. I have no real knowledge of electricity or electronics, but I know transistors are very fundamental so if you squint a bit, you might say this is what we set in motion when we program, or even just use a computer! Or at least some of it. Not knowing enough to benefit from it I learned nothing, and don't regret a second of that.

Thanks, I have an EE education, but I didn't really understood what charges were doing in a BJT. I can use them and apply the formulas, but I never really "grokked" them. This makes it clearer.

it kind of looks unrealistic that there's so little flow, but I guess that makes sense for micro-sized transistors, larger ones that can handle several amps at high voltage should behave differently and would be a rather interesting comparison.
