David T. Zihe, B.S.		Undergraduate Researcher
	David's work was aimed at designing and building a test bed for future cathodoluminescent phosphor screen testing. After graduation, David moved on to Case Western Reserve for his graduate studies.
Joe Riquelme, B.S.			Undergraduate Researcher
	Joe's work was the design of various high voltage power supplies. Variable DC power supplies of 0-5kV and 0-12kV are used for field emission light sources. Pulse generators producing 300V and 12kV are used for thermionic and field emission. Pulse generators are preferable to DC power for the purpose of prolonging the lifetimes of phosphor light sources.
Mitchell Cao, M.S.		Title of Thesis: Cathodoluminescent Phosphor Field Emission Light Source with Reticulated Vitreous Carbon Cathode
Mitchell's work included the development of a cathodoluminescent phosphor field emission light source. Field emission light sources offer a robust and low-cost alternative to traditional light sources such as incandescent and fluorescent light bulbs, LEDs, and lasers. Manufacture requires little microfabrication technology and can be adapted for emission at various wavelengths with little changes in device design. Applications include high efficiency lighting, light sources for gas sensors, and pump sources for optical amplifiers. Mitchell also worked on the calibration process for the surface treatment of reticulated vitreous carbon for its use as a field emission cathode. Mitchell is current working at NVIDIA Corporation as a Hardware Engineer and can be reached at mitchellcao@gmail.com
Yu Wang, Ph.D.			Postdoctoral Researcher
Yu was working on an x-ray detector based on Si field-emission tip technology. The x-ray is first converted to EHPs in the substrate Si The electrons are emitted into vacuum from spatially-distinct nanoscale field emission tips fabricated on the back-side of the conversion layer, and detected using an imaging multi-channel plate (MCP). Yu is currently at the University of Pennsylvania.
