| abstract | AN INFRARED PHOTOEMITTER AND PROCESS FOR FABRICATING SAME WHEREIN A THIN METAL LAYER IS SANDWICHED IN A COMPOSITE STRUCTURE BETWEEN A SUITABLE PHOTOABSORTIVE SEMICONDUCTIVE LAYER AND A LOW WORK FUNCTION INSULATING LAYER. THE SEMICONDUCTIVE LAYER SERVES AS A PHOTON ABSORBER AND PHOTOELECTION SOURCE FOR THE DEVICE. THE INSULATING LAYER IS CHOSEN FOR ITS LOW WORK FUNCTION. THE METAL INTERLAYER ELIMATES THE HETERJUNCTION WHICH IN ITS ABSENCE WOULD EXIST BETWEEN THE SEMICONDUCTIVE AND INSULATING LAYERS AND THEREBY ELIMINATES THE RESTRICTION THAT SUCH HETEROJUNCTIONS IMPOSE ON THE EFFICIENCY AND WAVELENGTH RESPONSE OF PRIOR ART COMPOSITION PHOTOEMITTERS. |
