The luminescence emission characteristics of silicon optical nanocrystal memory device were described. A silicon optical nanocrystal memory device can be fabricated through ion implantation, which can be read and erased optical or electrically. The programmed logic state of the device is read optically by the detection of high or low photoluminescence intensity, which varies according to the average charge state of the nanocrystals embedded in the device. The device can also be programmed and erased electrically through charge injection and optically through internal photoemission.
