💫 Wannier-Mott Exciton Binding in Semiconductors

Visualize an electron-hole pair bound by screened Coulomb attraction inside a semiconductor, and see how dielectric screening and reduced mass set the exciton Bohr radius and its hydrogen-like Rydberg series.

The simulation shows an electron and hole orbiting each other under screened Coulomb attraction inside a semiconductor lattice, illustrating how the exciton Bohr radius and its Rydberg series of absorption lines emerge from the interplay of dielectric screening and reduced mass.

🔬 What It Demonstrates

🎮 How to Use

Adjust the dielectric constant and reduced-mass sliders to see the bound-state orbit expand or contract and watch the corresponding Rydberg energy levels and absorption line spacing update accordingly.

💡 Did You Know?

In cuprous oxide crystals, physicists have optically resolved exciton Rydberg states up to a principal quantum number of 25, creating electron-hole orbits nearly a micrometer across, among the largest hydrogen-like atoms ever observed in a solid.
