Wide BandGap Semiconductor Irradiation Characterization (WBGSIC)
This project aims to devise a novel method of determining the Total Ionizing Dose (TID) of wide-bandgap (WBG) metal-oxide-semiconductor-field-effect-transistors (MOSFETs) in LEO. Many studies exist that characterize the sum of gradual effects of TID using a heavy ion beam, but few have attempted to do this testing in space on a satellite in LEO. The approach is to design a payload that is part of a larger cube satellite system to record and transmit measurements for analysis. Three parameters are closely measured on silicon carbide (SiC) and gallium nitride (GaN) MOSFETs: gate-to-source threshold voltage (Vt), drain-to-source on-state resistance (RDS(on)), and temperature. The change in these three can characterize the effects of TID. If the design can transmit useful data for characterizing the effects of space radiation, researchers can use this method to test future devices and make better-informed decisions about electronic part selection for space.
