Quantum Dot MEG — Energy-Cascade & Phase Diagram (2D)

This 2D companion visualizes multiple exciton generation (MEG) as energy accounting rather than a 3D particle scene. A scrolling cascade timeline draws each absorbed photon as a bar whose height is its energy, banded against the same confinement-bandgap and MEG-threshold rungs used by the 3D lattice simulator, while a radius-vs-photon-energy phase diagram maps out the achievable exciton yield across the whole parameter space and traces the live confinement bandgap curve. The same Brus effective-mass bandgap model and probabilistic carrier-multiplication rule drive both views — only the representation is different: energy bookkeeping and parameter-space instead of falling spheres in a lattice.
