Field Emission - an overview ScienceDirect Topics
WebThe field emission characteristics were investigated and the emission sites imaged using photoelectron emission microscopy (PEEM). Electron emission from these Si FEAs … WebJul 17, 2007 · We have developed a new method for fitting the current-voltage (I-V) characteristics of the field emission arrays (FEAs) that may be operated at high current density. In recent experiments of... A field emitter array (FEA) is a particular form of large-area field electron source. FEAs are prepared on a silicon substrate by lithographic techniques similar to those used in the fabrication of integrated circuits. Their structure consists of a very large number of individual, similar, small field electron emitters, usually … See more The original field emitter array was the Spindt array, in which the individual field emitters are small sharp molybdenum cones. Each is deposited inside a cylindrical void in an oxide film, with a counterelectrode … See more Nano-Spindt arrays represent an evolution of the traditional Spindt-type emitter. Each individual tip is several orders of magnitude smaller; as a result, gate voltages can be … See more Essentially very small electron beam generators, FEAs have been applied in many different domains. FEAs have been used to create flat panel displays (where they are known as field emission displays (or "nano-emissive displays"). They may also be used in … See more An alternative form of FEA is fabricated by creating voids in an oxide film (as for a Spindt array) and then using standard methods to grow one or more carbon nanotubes (CNTs) in each void. It is also possible to grow "free-standing" CNT arrays.
