Abstract

Quantum size effects have been thoroughly investigated since advances in material synthesis made possible the growth of semiconductor heterostructures with atomic monolayer accuracy. In the optical domain the exciton Bohr radius a₀ is usually the relevant length scale, and quantum confinement dominates the optical properties of semiconductor structures of size L ^≤a₀^1,2 Here we present a new quantum size effect, apparent in the line shape of the Fano resonance.⁵
