  • Nanocrystal quantum dot memory devices
    Publication number: 20060221672
    Abstract: Memory devices and recordable media are disclosed that take advantage of memory effects in the electronic transport in CdSe nanocrystal (NC) quantum dot arrays. Conduction through a NC array can be reduced with a negative voltage and then restored with a positive voltage. Light can also be used to restore or even increase the NC array conduction. The switching of the conduction in CdSe NC arrays and found the behavior to be highly sensitive to the value and duration of the laser and voltage pulses.
