Diamond vacuum field emission devices
This article reports the development of (a) vertical and (b) lateral diamond vacuum field emission devices with excellent field emission characteristics. These diamond field emission devices, diode and triode, were fabricated using a self-aligning gate formation technique from silicon-on-insulator wafers using conventional siliconmicropatterning and etching techniques. High emission current N0....
متن کاملAluminum Gallium Nitride-based Solar-blind Ultraviolet Photodetectors
Dedication To my parents, Gary and Carol, and to my loving girlfriend Connie. v Acknowledgements I would like to express my gratitude to my supervising, Professor Joe C. Campbell, for showing me the exciting world of nitride-based optoelectronic devices. His wise advice and constant support has been the most important aspect of my research, inspiring all of the work I have accomplished. Joe Cam...
متن کاملEstimation of parameters in thermal-field emission from diamond
This paper reports on the behavior of electron field emission from diamond thin films at elevated temperatures. The study is motivated by the possibility of using these structures in high temperature electronics or direct energy conversion processes. Three diamond samples were tested: nanocrystalline diamond, crowned diamond tips, and peaked diamond tips. All samples displayed moderately effici...
متن کاملEnhanced Field Emission from Diamond Coated Molybdenum Emitters
The field emission characteristics of individual Mo emitters were measured before and after diamond deposition, as well as before and after annealing. After coating without annealing, the emission current increased dramatically. Subsequent annealing resulted in further increases in emission and improved current stability. After coating, the energy distribution of the emitted electrons was found...
متن کاملFar Ultraviolet Detector Standards
National Bureau of Standards Gaithersburg, MD 20899 A description is given of the NBS program in which special photodiodes for the far ultraviolet spectral region (5254 nm) are made available as transfer standards. These detectors are calibrated in terms of quantum efficiency (photoelectrons per incident photon) as a function of wavelength. Descriptions are also given of the calibration princip...
