Importance of Gas Heating in Capacitively Coupled Radiofrequency Plasma-assisted Synthesis of Carbon Nanomaterials
Tanvi Nikhar, Sankhadeep Basu, Shota Abe +4
In pursuit of diamond nanoparticles, a capacitively-coupled radio frequency (CCRF) flow-through plasma reactor was operated with methane argon gas mixtures. Signatures of the final…
Evidence of Gas Phase Nucleation of Nano Diamond in Microwave Plasma Assisted Chemical Vapor Deposition
Tanvi Nikhar, Sergey V. Baryshev
The mechanism of ballas like nano crystalline diamond formation (NCD) still remains elusive, and this work attempts to analyze its formation in the framework of activation energy (…
Ampere-class Bright Field Emission Cathode Operated at 100 MV/m
Mitchell Schneider, Emily Jevarjian, Tanvi Nikhar +4
High current bright sources are needed to power the next generation of compact rf and microwave systems. A major requirement is that such a source could be sustainably operated at…
Evidence for Anti-Dowell-Schmerge Process in Photoemission from Diamond
Tanvi Nikhar, Sergey V. Baryshev, Gowri Adhikari +1
A great number of metal and semiconductor photocathodes, which are of high practical importance for photoinjector applications, closely follow the 1/3 gradient Dowell-Schmerge (DS)…
Revisiting Effects of Nitrogen Incorporation and Graphitization on Conductivity of Ultra-nano-crystalline Diamond Films
Tanvi Nikhar, Robert Rechenberg, Michael Becker +1
Detailed structural and electrical properties of ultra-nano-crystalline diamond (UNCD) films grown in H/CH/N plasma were systematically studied as…
Systematic benchmarking of planar nitrogen-incorporated ultrananocrystalline diamond field emission electron source: rf conditioning and beam spatio-temporal characteristics
Jiahang Shao, Mitchell Schneider, Gongxiaohui Chen +8
Planar nitrogen-incorporated ultrananocrystalline diamond, (N)UNCD, has emerged as a unique field emission source attractive for accelerator applications because of its capability…
Field Electron Emission Induced Glow Discharge in Nanodiamond Vacuum Diode
Stanislav S. Baturin, Tanvi Nikhar, Sergey V. Baryshev
The present letter extends the prior findings on self-induced heating of solid state field emission devices. It was found that a vacuum diode (base pressure Torr), th…
