Abstract
In this work, GaN-on-Si MIS-HEMT DC characterization results are presented from 4 K to 550 K, to observe the device’s behavior for space applications. The enhancement in threshold voltage $\left(\mathrm{V}_{\text {th }}\right)$, transconductance $\left(\mathrm{g}_{\mathrm{m}}\right)$, and ON resistance ($\mathrm{R}_{\mathrm{ON}, \text { spec }}$) of the device are analyzed as a function of temperature. It is observed that there is no carrier freeze-out effect at 4 K, nor any self-heating effect at 550 K, making it a perfect device for use in quantum computing and space applications.
