Semisim - Visualize transistor charge carrier dynamics
Show HN: I made some transistor animations
Semisim is an innovative semiconductor simulator that brings complex transistor operations to life through vivid animations. It visualizes the movement of electrons and holes, clearly distinguishing between diffusion and drift currents in NPN BJTs, n-ch MOSFETs, and n-ch JFETs. By using color-coded dots for charge carriers and flashes for recombination events, it transforms abstract physics into an intuitive visual experience. Whether you are a student struggling to grasp internal device physics or an engineer needing a quick reference, Semisim offers a unique window into the microscopic world of semiconductors, making the invisible mechanics of modern electronics easy to understand.
This is the most accurate way of depicting charge carrier motion, offering a clear visual bridge between complex physics and intuitive understanding.

This would have been invaluable when I did my EEE degree many years ago. I use to draw the charge carries instead.

That's really cool. I am again planning to focus more on maths n physics...Hope it helps along..thanks

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.
