Quantum Dot Ligand Exchange — 2D Hex-Lattice & Kinetics View

Every colloidal quantum dot is a nanocrystal core wrapped in a shell of organic ligand molecules, and that shell is the difference between a bright emitter and a dark one. This 2D build represents the shell as an unrolled hexagonal lattice of individual binding sites, each one running its own stochastic Langmuir adsorption/desorption process frame by frame, and plots the resulting coverage θ(t) and measured photoluminescence quantum yield as live strip charts next to it — the same physics as the 3D sphere, computed independently site-by-site and shown as the surface map and kinetics traces a surface chemist would actually draw on a whiteboard.
