| Abstract: | Optical injection of electrons from CdSe nanocrystals into amorphous semiconductors can be used to optically control the electron density in trap-rich conduction bands. For the specific example of polycrystalline C60, we show that important parameters of the density of trap states below the mobility edge can be retrieved. |
