Title: Innovations of Marcus A Schildbach
Introduction
Marcus A Schildbach is a notable inventor based in Livermore, CA (US). He holds a total of 5 patents that showcase his contributions to the field of technology, particularly in the area of field emission displays and thin film technologies.
Latest Patents
One of his latest patents is a junction-based field emission structure for field emission displays. This invention involves creating junctions by depositing a semiconducting or dielectric, low work function, negative electron affinity (NEA) silicon-based compound film (SBCF) onto a metal or n-type semiconductor substrate. The SBCF can be doped to become a p-type semiconductor. A small forward bias voltage is applied across the junction, allowing electron transport from the substrate into the SBCF region. Upon entering the NEA region, many electrons are released into the vacuum level above the SBCF surface and accelerated toward a positively biased phosphor screen anode, lighting up the phosphor screen for display. To turn off the display, the applied potential across the SBCF/substrate can simply be switched off.
Another significant patent involves the generation of low work function, stable compound thin films by laser ablation. This process synthesizes compound thin films with low work function by simultaneously laser ablating silicon and thermally evaporating an alkali metal into an oxygen environment. The resulting compound thin film may consist of Si/Cs/O, and its work functions can be varied by adjusting the silicon/alkali metal/oxygen ratio. The stability of these compound thin films has been confirmed up to 500°C, as measured by x-ray photoelectron spectroscopy (XPS). These films can be utilized in various applications, including solar cells, field emission flat panel displays, electron guns, and cold cathode electron guns.
