For
Students studying semiconductor physics
Worth noticing
The maker says some demos adapt Dr. Sean Rommel’s earlier work, while others are personal learning projects; the site disclaims RIT affiliation.

Field notes

The catalog groups visualizations by device or physical effect, with descriptions naming outputs such as C-V curves, spectral response, and transient minority-charge analysis. It also identifies material choices for the photosensitivity demo and distinguishes adaptations of earlier work from the maker’s own experiments; the maker says errors may be present.
