Abstract
Field emitter arrays (FEAs) have the potential to operate at high frequencies and withstand harsh environments, such as radiation and high temperatures. However, they are sensitive to gaseous environments. This study examines the impact of different gas environments on silicon (Si) and gallium nitride (GaN) FEAs. To investigate the failure mechanisms, a vacuum system was designed and fabricated to monitor emission uniformity using a phosphor screen. Additionally, a vacuum system was created to introduce high-purity gases into the chamber while operating the devices. The results indicate that both types of FEAs are susceptible to oxidizing environments. Argon (Ar) did not significantly affect the emission current, whereas nitrogen (N2) enhanced the current.
