Band diagram of a nanocrystalline material embedded in a matrix material with larger bandgap. Conduction band discontinuity (qΦc), valence band discontinuity (qΦv), and inter-nanocrystal distance (d) are indicated. Electron-hole pair generation with incident light (hν) and approximate expression of nanocrystal-to-nanocrystal tunneling probability (T) are also shown.
