ABSTRACT:
A semiconductor nanocrystal can have a barbell shape. The nanocrystal can include two semiconductor materials selected so that upon excitation, one charge carrier is substantially confined to the one semiconductor material and the other charge carrier is substantially confined to the other semiconductor material.
