    A realistic four-pixel CIS assembly with material boundaries and mesh is simulated to examine crosstalk between pixels (top). Following illumination of the top pixel, the optical field is mapped in units of volts/m (center). The analysis confirms that crosstalk between pixels (in terms of the optical generation rate, cm-3s-1) is a critical design issue (bottom).

    The horizontal main chamber in this COLTRIMS system houses the spectrometer. A cold beam of molecules is created in the lower portion of the vertical tube and fed through the laser focus in the main chamber, where the electrons can be extracted from and recollided with parent molecules during the same pulse cycle to create sequential “moving frames” of chemical processes.

    In an excitonic integrated circuit (EXIC) with three exciton optoelectronic transistors (EXOTs), a directional switching scheme uses voltage differentials at one electrode (colored spot) to channel “indirect exciton” flux (arrows) toward electrodes to the left and right (left top). In another scheme, equal voltages direct the flux from a central electrode, creating a three-beam star geometry (left center, and right). A third scheme demonstrates the merging of indirect exciton flux (left bottom).

    Sony’s 3-mm-thick XEL-1 organic-light-emitting-diode (OLED) TV received SID’s 2008 Gold Award for Display Device of the Year. While the XEL-1 may be expensive at $2500 (considering it is only 11 inches on the diagonal), OLED technology is here to stay, as it promises better picture quality, lower power consumption, and hopefully, lower prices as numerous companies enter the market and improve manufacturing capabilities.
