Abstract
Nanoscale vacuum/air channel electron tubes (VETs) keep emerging owing to their superior performance in high-temperature and high-frequency working environments. However, in VETs the edge field of the gate with inferior modulation efficiency, nonnegligible leakage or accumulation, and poor compatibility with integrated circuits (ICs) technology limits the realization of VET IC. In this work, an original cathode-modulated VET (CMVET) is proposed, which can efficiently control the field emission current of the cathode by directly regulating the electron density of the cathode by back-gate, resulting in regulating the anode current. As a result, we obtain a transconductance of
$4.6 \; \mu $
S and a suppressed gate leakage current of no more than
$10^{-{11}}$
A for the CMVET device, which is completely fabricated by traditional microelectronic process, being compatible with IC processes. On the basis of this strategy, it is promising to realize the CMVET IC with great resistance to high frequency, high temperature, and high radiation.
期刊介绍:
IEEE Transactions on Electron Devices publishes original and significant contributions relating to the theory, modeling, design, performance and reliability of electron and ion integrated circuit devices and interconnects, involving insulators, metals, organic materials, micro-plasmas, semiconductors, quantum-effect structures, vacuum devices, and emerging materials with applications in bioelectronics, biomedical electronics, computation, communications, displays, microelectromechanics, imaging, micro-actuators, nanoelectronics, optoelectronics, photovoltaics, power ICs and micro-sensors. Tutorial and review papers on these subjects are also published and occasional special issues appear to present a collection of papers which treat particular areas in more depth and breadth.
