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.
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.
Sliders for dielectric constant and electron-hole reduced mass
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.
