Abstract

A semiconductor structure includes a nanocrystalline core comprising a first semiconductor material having a first bandgap, and a nanocrystalline shell comprising a second semiconductor material different than the first semiconductor material at least partially surrounding the nanocrystalline core, the second semiconductor material having a second bandgap greater than the first bandgap.
