Engineering strong-field phenomena : from attosecond pulse characterization to nanostructured electron emitters
… generate attosecond pulses of both photons and electrons are becoming readily available. Furthermore, through the coupling of these optical fields to nanostructures that further enhance peak field strengths, a new generation of electron emitters and "light-speed" electronics are now emerging. …

An analytical framework for field electron emission, incorporating quantum- confinement effects
As field electron emitters shrink to nanoscale dimensions, the effects of quantum confinement of the electron supply and electric field enhancement at the emitter tip play a significant role in determining the emitted current density (ECD). Consequently, the Fowler-Nordheim (FN) equation, which …

Xray Generation by Field Emission
… unchanged. From the inception of thermionic electron sources, which, due to simplicity of fabrication, remain central to almost all X-ray applications at this time, there have been few fundamental technological advances. The emergence of new materials and manufacturing techniques has created …

Theory and modeling of field electron emission from low-dimensional electron systems
… have succeeded in fabricating nanoscale field electron emitters in a variety of geometries and materials for use as electron sources in vacuum nanoelectronic devices, theory and modeling of field electron emission have not kept pace. Treatments of field emission which address individual …

Electroforming and electron emission in metal-borosilicate glass-metal structures
… show electroforming effects and subsequently electron emission, voltage-controlled negative resistance, electroluminescence, and switching phenomena. Previous work in this field is reviewed. By making certain modifications to the filamentary conduction theory of Dearnaley, the time dependence …

Extrusion Printing of Carbon Nanotube Inks, from Rheology to Electronics
Printed electronics rely on the deposition of conductive liquid-based inks into continuous lines and films, typically on polymeric substrates. Among candidate conductive fillers for use in electronic inks, carbon nanotubes (CNTs) have high conductivity, low density, processability at ambient …
