21. A 1D particle-in-a-box calculation of electron and hole wavefunctions for our dot/rod nanocrystals gave an overlap factor for electron and hole wavefunctions in excess of 0.9. Electron and hole masses in CdSe are respectively 0.12 me and 0.45 me; conduction and valence band offsets are 0.27 eV and 0.51 eV, respectively.
