Abstract:

We developed novel carbon nanotube electron beams with Carbon Nanotube (CNT) cold cathodes. The electron beam shows more than 90% electron transmission ratio through gate electrode, resulting higher anode current and lower thermal damage on gate electrode. The electron beam shows anode current more than 100 mA with DC pulse driving at less than 1 cm2 area. Also, life time of the beam shows more than 300 hrs in DC driving. We fabricated electron beam modules with the CNT cold cathode and applied for medical and solid state devices. For medical devices, we fabricated glass sealed x-ray tubes with the electron beam and evaluated its performances, resulting high resolution x-ray. For solid state devices, we irradiated the electron beam on semiconducting, and insulating thin films. Then, we observed phase changes on those thin films and generation of luminescence from those films by phase changes. Detail of electron beam fabrication process with CNT cold cathode, performance of electron beam, characteristics of x-ray tubes with the beams and beam irradiation will be presented.
