A molecular overlayer with the Fibonacci square grid structure

Recorded summary

Scanning tunnelling microscopy shows fullerene molecules arranged in a Fibonacci square grid on an Al–Pd–Mn quasicrystal surface. Selective adsorption links the overlayer geometry to substrate sites.

Recorded limitations

This is a specific engineered material system. It does not demonstrate Fibonacci organisation of living cells or general molecular recognition.
