Fundamental Studies For Nanoscale Vacuum Electronic Emission Devices
Abstract
Electronic device miniaturization continues [1], with its focus on faster speeds, more compact andintegrated structures, radiation-resistance and thermal stability, increased device reliability androbustness against external perturbations. The latter become important for space environments ordefense applications. At the electronic component level, solid-state devices have attractedconsiderable attention over the past few decades given that such devices are scalable without lossof performance, consume extremely low power per function, and can be easily integrated intofunctional circuits enabling large-scale manufacturing. However, the vacuum state promisessuperior electron transport compared to semiconductor electronics since collisions and scatteringwithin the crystal lattice are completely avoided. The immunity to noise in vacuum electronics isalso an advantage. Also, electronic velocities in vacuum can be much higher than the saturationvelocity in even the most high-mobility and/or quantum scaled semiconductors. Furthermore,vacuum devices offer more stable operation as compared to solid-state devices under extremetemperature and radiation environments [2, 3].
