    • Incomplete NC monolayers containing large defect areas do show GaN p-n junction emission resulting from "short circuit" paths throughout the NC region.

    • As the diameter of a CdSe NC decreases, its band gap increases because of the effects of quantum confinement. In CdSe NCs, this increase occurs primarily by a shift of the NC conduction band edge to higher energies, which moves it closer to the conduction-band offset of GaN. This trend limits the applicability of GaN as the electron injection layer to NCs with radii larger than 0.8 nm corresponding to emission wavelengths longer than ca. 440 nm (blue color). This estimation indicates that our approach can potentially be used with CdSe NCs emitting over the entire range of visible wavelengths from red to blue.

    • The reduction in the radiative lifetime from the usual 20 ns is the result of NC encapsulation in a high index material (n = 2.2).
