Bright Spatially Coherent Beam from Carbon Nanotube Fiber Field Emission Cathode
Taha Y. Posos, Sergey V. Baryshev
Large area carbon nanotube (CNT) cathodes made from yarns, films or fibers have long been promising as next generation electron sources for high power radio frequency (rf) and micr…
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…
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…
Field emission microscopy of carbon nanotube fibers: evaluating and interpreting spatial emission
Taha Y. Posos, Steven B. Fairchild, Jeongho Park +1
In this work, we quantify field emission properties of cathodes made from carbon nanotube (CNT) fibers. The cathodes were arranged in different configurations to determine the effe…
