Project:	Dielectric problems with MgB2 superconducting microdevices (JPL AO No. 15258)
Disciplines:	Physics/Applied Physics, Materials Science
Mentor:	Changsub Kim, (JPL), chang.sub.kim@jpl.nasa.gov, Phone: (818) 354-4899
Background:	Development of high-frequency superconducting devices with high critical temperature superconductors like MgB2 is of major interest for JPL and NASA. Two major bottlenecks in developing such microdevices come from (1) immature fabrication processes and (2) shorts and imperfections in dielectric layers. This project aims to develop fabrication processes and dielectric materials for MgB2 microdevices at JPL’s Microdevices Laboratory (MDL).
Description:	The student will deposit dielectric films, fabricate and characterize MgB2 microstrip devices, and analyze measurement data to develop MgB2 superconducting microdevices.
