3D Quantum Dot — Electron Probability Cloud & Confinement

Interactive 3D quantum dot: shrink or grow a spherical semiconductor nanocrystal and watch its electron probability-density cloud visibly compress or spread as the real particle-in-a-sphere confinement energy and emitted photon color respond live.

ControlsMaterial buttons (CdSe / CdS / PbS / InP) switch the bulk bandgap and reduced effective mass; dot radius slider (R, 0.6-6 nm) rescales the confining sphere and resamples the probability-density point cloud from the real sin²(πr/R) radial distribution; probability-cloud toggle shows or hides the |ψ(r)|² point cloud versus the bare confining sphere; drag to orbit the camera around the dot.

An actual 3D semiconductor quantum dot rendered with Three.js: its electron probability-density cloud (the real particle-in-a-sphere |ψ(r)|² wavefunction shape) visibly compresses as the dot shrinks, driving up the confinement energy and shifting the emitted photon color toward blue.
