Abstract

Strong quantum confinement in InP is observed to significantly reduce the separation between the direct and indirect conduction band states. The effects of three-dimensional confinement are investigated by tailoring the initial separation between conduction band states using quan um dots (QDs) of different sizes and hydrostatic pressure. Analyses of the QD emission spectra show that the X_1c states are lowest in energy at pressures of ˜ 6 GPa, much lower than in the bulk. The transition to the X_1c states can be explained by either a sequence of Τ-L and L-X crossings, or by the crossover between strongly coupled Τ and X states.
