Miniaturized Wide-Range Field-Emission Vacuum Gauge Short Communication
Miniaturized vacuum gauges (MVGs) for the measurement range 5.7x10-7 to 1.1x10-2 mbar were fabricated in a selfaligned approach using focused ion beam (FIB) nanoma‐ chining and reactive ion etching (RIE). The MVG consists of two properly insulated electrodes integrated on top of an atomic force microscopy (AFM) tip, forming a coaxial embodiment. The special design enables us to vary the cathode...
متن کاملDiamond vacuum field emission devices
This article reports the development of (a) vertical and (b) lateral diamond vacuum field emission devices with excellent field emission characteristics. These diamond field emission devices, diode and triode, were fabricated using a self-aligning gate formation technique from silicon-on-insulator wafers using conventional siliconmicropatterning and etching techniques. High emission current N0....
متن کاملSiegel Gauge in Vacuum String Field Theory
We study the star algebra of ghost sector in vacuum string field theory (VSFT). We show that the star product of two states in the Siegel gauge is BRST exact if we take the BRST charge to be the one found in [1], and the BRST exact states are nil factors in the star algebra. By introducing a new star product defined on the states in the Siegel gauge, the equation of motion of VSFT is characteri...
متن کاملWide-range Vacuum Measurements from MWNT Field Emitters Grown Directly on Stainless Steel Substrates
The field emission properties and the vacuum measurement application are investigated from the multi-walled carbon nanotubes (MWNTs) grown directly on catalytic stainless steel substrates. The MWNT emitters present excellent emission properties after the acid treatment of the substrate. The MWNT gauge is able to work down to the extreme-high vacuum (XHV) range with linear measurement performanc...
متن کاملMiniaturized high-resolution wide-field contact lens for panretinal photocoagulation
BACKGROUND AND OBJECTIVE We describe a miniaturized lightweight high-refractive-index panretinal contact lens for diagnostic and therapeutic visualization of the peripheral retina. INSTRUMENT DESIGN The miniaturized high-resolution wide-field contact lens includes three optical elements in a light (15 g) and miniaturized (16 mm footplate, 24 mm external aperture, and 21 mm vertical height) ca...
