Several disclosures covering Carbon Nanotube (CNT) based devices for Field Emitter (FE) applications have been published, none of which have shown commercial viability. As a result of our research and development, El-Mul Technologies has recently gained knowledge of some critical factors which enable semi-commercial manufacturing of single CNT-based FE devices that are useful for a wide variety of applications. The object of this talk is to present this novel device and discuss its key characteristics. Our proprietary technology combines conventional semiconductor manufacturing processes with nanoscale innovations to yield scalable, high performance electron micro-gun arrays. The technology provides the ability to manufacture tailored emitters for either low current, narrow angle fine beams or high current broad beams in a controlled manner. In both configurations, the device demonstrates classic FE behavior, expressed by an exponential IV profile with exceptionally low turn on voltage (20-50 volts), and fast rise of current versus operating voltage (up to 100 nano amps per CNT). Evidence of these capabilities will also be presented using Field Emission Microscopy (FEM). In addition, issues such as lifetime, stability, and scalability parameters of this device will be discussed.
