The technology in this portfolio relates to a field emission
device comprising a cathode having an emission region for
electrons.  The field emission device is embodied for
generating technically useful electron currents at a voltage which
is as low as possible, in such a way that the emission region has
an arrangement of a plurality of individually positioned or
positionable atoms or molecules. As such, this technology could
have practical applications in a variety of markets.  The
field emission device may be usable in a field emission microscope,
in a scanning tunneling microscope, in an atomic force microscope,
or for ionizing gases.  Furthermore, the disclosed field
emission device could not only serve in the field of illuminants or
backlights, but could also be utilized on circuit boards, in
microdevices, and in the field of data carriers.  Additional
related markets include measuring sensors, hand-held x-ray
fluorescence analysis devices, in x-ray devices, and in computer
tomography.

“When related to the x-ray market, the patents of this portfolio
solve many of the challenges associated with traditional products
such as limited resolution, high operating temperature, and slow
response time,” commented Dean Becker, CEO of ICAP Ocean Tomo. This
