Confirmation of Transit-Time Limited Field Emission in Advanced Carbon Materials with Fast Pattern Recognition Algorithm
Taha Y. Posos, Oksana Chubenko, Sergey V. Baryshev
An accurate estimation of the experimental field-emission area remains a great challenge in vacuum electronics. The lack of convenient means, which can be used to measure this para…
Monte Carlo Modeling of Spin-polarized Photoemission from p-doped GaAs Activated to Negative Electron Affinity
Oksana Chubenko, Siddharth Karkare, Dimitre Dimitrov +4
The anticorrelation between quantum efficiency (QE) and electron spin polarization (ESP) from a p-doped GaAs activated to negative electron affinity (NEA) is studied in detail usin…
Fast Pattern Recognition for Electron Emission Micrograph Analysis
Taha Y. Posos, Oksana Chubenko, Sergey V. Baryshev
In this work, a pattern recognition algorithm was developed to process and analyze electron emission micrographs. Various examples of dc and rf emission are given that demonstrate…
Theoretical Evaluation of Electronic Density-of-states and Transport Effects on Field Emission from -type Ultrananocrystalline Diamond Films
Oksana Chubenko, Stanislav S. Baturin, Sergey V. Baryshev
In the nitrogen-incorporated ultrananocrystalline diamond ((N)UNCD) films, representing an -type highly conductive two-phase material comprised of diamond grains and $sp^…
Electron Emission Area Depends on Electric Field and Unveils Field Emission Properties in Nanodiamond Films
Oksana Chubenko, Stanislav S. Baturin, Kiran Kumar Kovi +2
In this paper we study the effect of actual, locally resolved, field emission (FE) area on electron emission characteristics of uniform semimetallic nitrogen-incorporated ultranano…
Scanning probe microscopy and field emission schemes for studying electron emission from polycrystalline diamond
Oksana Chubenko, Stanislav S. Baturin, Sergey V. Baryshev
The letter introduces a diagram that rationalizes tunneling atomic force microscopy (TUNA) observations of electron emission from polycrystalline diamonds as described in recent pu…
