    • Numerical calculations show a relatively uniform field across the substrate surface at a distance farther than 1 μm from either electrode (the field profile varies with σ = 7% of the mean).

    • Formally, what is measured in these experiments is actually the difference between the excited-and ground-state dipole (polarizability). For simplicity in discussion, we refer to this value as the excited-state dipole (polarizability). This is a reasonable assertion because, to a first approximation, any structural (ground-state) dipole (polarizability) should be relatively unaffected by the presence of a delocalized excitation.

    • Data were collected from 47 single QDs for the 37.5 Å overcoated sample and from 57, 83, 74, and 16 single QDs for the 37.5 Å, 29 Å, 26 Å, and 22 Å standard samples, respectively. Calculations included screening by the CdSe core and ZnS shell as necessary.
