Recent advances in genomic sequencing and genomic medicine are reshaping the landscape of clinical care. As a screening modality, genetic sequencing has the potential to dramatically expand the clinical utility of newborn screening (NBS), though sign

We demonstrate field emission from planar graphene edges fabricated using a new method. The device uses narrow cantilevered metal beams to support the graphene. To date we have measured emission currents over 10μA from edges less than 50μm long, th

We report electron field emission from planar graphene edge sources with integrated gate and drain electrodes, forming a field effect transistor with vacuum transport parallel to the substrate surface. The drain-source voltage required to produce a g

We demonstrate field emission from an integrated three-terminal device using a suspended planar graphene edge as the source of vacuum electrons. Energy spectra of the emitted electrons confirm the field-emission mechanism. The energy spectra produced

We have considered the opportunities and challenges of fabricating a planar vacuum transistor using the edge of a single layer graphene sheet as a field emission electron source. The emission current needed to produce significant gain and power at mm

Secondary-electron-emission current measured from high-purity, single-crystal CVD diamond is found to increase when 3.1-eV photons are incident on the hydrogenated surface. Energy spectra indicate that the sub-gap illumination causes the band levels

A diamond current amplifier is being developed that can be biased to generate an internal electric field needed for high transport efficiency and emission gain. In the process, a bonded diamond structure has been successfully fabricated that provides

We report progress in mounting small thin diamond sheets over holes in larger substrates in a manner that allows electron beam amplification. In addition to a physical mount, our bonding method must be compatible with the creation and maintenance of

We report on electron emission from cesiated GaN n–p junctions in forward bias. Surface electric fields ∼3 V/μm caused a fivefold increase in emission current. Initial maximum currents in excess of 200 nA degrade to 50 nA due to charge trapping
