ABSTRACT:
Image formation is effected on the basis of the generation and erasing of color centers in a semiconducting oxide layer disposed between an electron injection layer and a hole injection layer. An image is formed by the trapping of electrons in color-center-promoting structural defects in the oxide layer when a potential difference is applied selectively across the oxide layer with the electron injection layer being negatively biased relative to the hole injection layer so as to enforce the dual injection of electrons and holes into the oxide layer. The image is erased by applying a potential difference of opposite polarity across the electron and hole injection layers.
