Devices based on the field emission process have many applications as a low power source of electrons. The low mass and volume benefits that are also conferred by micro fabrication are very attractive to the designers of space instrumentation where m

We outline the design, construction and testing of a field effect neutralizer, which provides a source of up to 6 mA of electron emission to maintain charge neutrality for the LISA Pathfinder mission spacecraft. The low mass, low power neutralizer us

As part of a program for the development of a space-qualified submillimeter-wave mixer operating in the region of one terahertz, the authors have developed processes for the fabrication of submicron whole-wafer tunnel junctions. Using the self-aligne

The basic structures of MEMS sensing elements are mechanical parts like microbridge, microcantilever and micromembrane. One way of characterizing the performance of these flexible microcomponents is by defining their relevant stiffness. Stiffness is

We report the fabrication and characterization of well-defined gated Si microtip arrays with diamond-like carbon (DLC) apexes. It was found that for a 40/spl times/40 gated Si tip array with DLC apexes, an emission current density up to 0.23 A/cm/sup
