The present investigation paves the pathway to the fabrication of self-organized Si nanostructure-based highly stable cold cathode electron emitting devices having fascinating low turn-on and threshold fields along with extremely high field enhancement factors and high stability for use in nanoscale electronic devices.

Furthermore, finite element electrostatic field-based simulations reinforce the experimental observations. Cold Cathode Installation Orientation Any Measurement Range 3.0 x 10 -10 - 5.0 x 10 -3 Torr Set Point Range 1.0 x 10 -9 - 1. In addition, in-depth dual pass tunnelling current microscopy measurements demonstrate that the Au-NPs on the apexes and sidewalls of Si-NFs act as cold cathode electron emission sites which help to improve the turn-on and threshold fields for Au-NP-decorated Si-NFs in comparison to their as-prepared counterparts where electron emission takes place mostly from their sidewalls and valleys. A cold cathode fluorescent lamp (CCFL) is a lighting system that utilizes both fluorescence and electron discharge in order to produce light. Kelvin probe force microscopy studies reveal that tunability in the work function of Au-NP-decorated Si-NF samples depends on the dimension and growth-angle of gold nanoparticles (Au-NPs). It is true that heating the cathode takes a fair amount of energy, but it is an easy device to make. It is interesting to note that even as-prepared Si-NFs offer hitherto unseen low turn-on fields (as low as 0.58 V μm −1) and threshold electric fields (0.66 V μm −1) – so far as silicon-based nanostructures are concerned. This is called 'cold cathode field emission' and is well known. Logisys CLK12BL2 Dual Cold Cathode Light Kit, Blue. The term Cold Cathode refers to a cathode that is not electrically heated by a filament. Logisys 12' Dual Cold Cathode Kit, 3.0mm Tube Diameter, 680V Output Voltage, Green. CPM Delta 1 35111 12 35110 Brightlab Junior Safelight 11W Universal Red Bulb. This report presents cold cathode electron emission from Au-NP-decorated ensembles of self-organized silicon nanofacets (Si-NFs) having fascinating ultralow turn-on fields (as low as 0.27 V μm −1) and remarkably low threshold electric fields (as low as 0.37 V μm −1) with outstanding stability. In the cold cathode gauge (CCG) it is a circulating space charge current of electrons trapped in crossed electric and magnetic fields.

However, the fabrication of stable Si nanostructure-based cold cathode electron emitters with ultra-low threshold fields is a challenging task. A cold cathode is not electrically heated by a filament and is used in neon lamps, vacuum tubes etc. For instance, hierarchical growth of self-assembled noble metal nanoparticles on self-organized nanostructured materials offers the advantage of fabricating low threshold cold cathode electron emitters. In order for a stable arc to form, there must be a minimum current passing through the arc. Stocked items can usually be found in the “Ordering Table” and can generally be shipped same day.įor help with selecting a gauge, please use the KJLC Selection Guide, refer to the Gauging Tech Notes, or simply email for further information.Fabrication of highly dense conical nanostructures and their subsequent controlled metallization make them ideal candidates for enhancing cold cathode electron emission efficiency. The cold cathode source is the most common cathodic arc source for film deposition.
Please see the individual product pages for further information. On top of standard pressure measurement, KJLC can also offer complete solutions for process control, covering Capacitance Manometers, Mass Flow Controllers, and Throttle Valves. Whether the application require a simple Thermocouple Gauge to reach medium vacuum, a Cold Cathode gauge to reach UHV, or a Combination gauge to measure the entire range, KJLC can cover it. Lesker Company ® offers a wide variety of vacuum gauges and transducers that cover a range from UHV to ATM.
