1.1.1: The purpose of this research project is to advance the fundamental physics-based understanding of vacuum field emission in nanoscale emitters, predict and probe the electrical response of nanoscale emitter arrays, analyze surface physics including effects due to incident ion impact, characterize transport in response to external field and/or photoexcitation driver, and the possibility of nanoemitter degradation to Maxwell stress and local heating. The modeling will be tightly coupled with experimental efforts underway in the US for greater synergies. The primary aim would be to facilitate direct head-to-head comparisons for model fine-tuning and to get a more insightful understanding of the inherent processes. Though fundamental studies are a primary target, the results should also yield optimization scenarios and rough ″safe operating″ parameter ranges to lower degradation.
