Reza Farsad Asadi: Miniaturized Vacuum Tubes

A Nanoscale Vacuum-Channel Transistor (NVCT) is a transistor based on field emission that the electron channel is a vacuum. These transistors are nanoscale versions of vacuum tubes. Because the channel is a vacuum, they can potentially be faster than traditional solid state transistors. Also, they can be expected to be less susceptible to harsh environments compare to the solid state transistors. However, they have shown instability over time and they require high vacuum to operate. This project on investigating the lifetime and instability of field emitters over time.
