The mechanism of ballas-like nanodiamond formation still remains elusive, and this work attempts to analyze its formation in the framework of activation energy (Ea) of nanodiamond films grown from a H2/CH4 plasma in a 2.45 GHz chemical vapor depositi

This paper discusses the trends and tradeoffs between transverse σ_{x} and longitudinal σ_{z} bunch dimensions, rf injector gradient, bunch charge, and intrinsic electron mean transverse energy (MTE), where all can be chosen to be independent, and

High-current bright sources are needed to power the next generation of compact rf and microwave systems. A major requirement is that such sources could be sustainably operated at high frequencies, well above 1 GHz, and high gradients, well above 100

Traditional FETs are transit time-limited in maximum frequency. The plasmonic FET concept solves the frequency limitation with behavior governed by oscillations in the surface carrier plasma where break up instability and signal amplification at ultr
