    Abstract: This invention discloses novel nanocomposite material structures which are strong, highly conductive, and fatigue-resistant. It also discloses novel fabrication techniques to obtain such structures. The new nanocomposite materials comprise a high-conductivity base metal, such as copper, incorporating high-conductivity dispersoid particles that simultaneously minimize field enhancements, maintain good thermal conductivity, and enhance mechanical strength. The use of metal nanoparticles with electrical conductivity comparable to that of the base automatically removes the regions of higher RF field and enhanced current density. Additionally, conductive nanoparticles will reduce the surface's sensitivity to arc or sputtering damage. If the surface is sputtered away to uncover the nanoparticles, their properties will not be dramatically different from the base surface. Most importantly, the secondary electron emission coefficients of all materials in the nanocomposite are small and close to unity, whereas the previously used insulating particles can produce significant and undesirable electron multiplication.

    Abstract: A mechanically stable and oriented scanning probe tip comprising a carbon nanotube having a base with gradually decreasing diameter, with a sharp tip at the probe tip. Such a tip or an array of tips is produced by depositing a catalyst metal film on a substrate (10 & 12 in FIG. 1(a)), depositing a carbon dot (14 in FIG. 1(b)) on the catalyst metal film, etching away the catalyst metal film (FIG. 1(c)) not masked by the carbon dot, removing the carbon dot from the catalyst metal film to expose the catalyst metal film (FIG. 1(d)), and growing a carbon nanotube probe tip on the catalyst film (16 in FIG. 1(e)). The carbon probe tips can be straight, angled, or sharply bent and have various technical applications.

    Abstract: A micro-electro-mechanical systems (MEMS) device is presented that can read very high density magnetic media and very high density CD ROMs. Both the magnetic and optical read heads comprise one or more cold cathode MEMS e-beam cells. The e-beams are deflected according to the data bit being interrogated and the state of that bit is determined by a detector. Large arrays of such cells can simultaneously read large areas of the memory media. Arrays of such MEMs detectors can comprise a plurality of “steerable” e-beam emitters that can be directed to interrogate specific data sites on the magnetic media. Thus, in some cases, the media can remain stationary. Densities of 200 gigabits per square inch or more and read speeds greater than 1000 times faster can be achieved.
