What is it about?

Why do gallium oxide devices with strong theoretical radiation resistance still degrade in the space radiation environment? This work gives the reasons from the perspective of defects. Why wording in the radiation environment accelerates degradation compared to leaving it alone. This paper presents its mechanism through experiments and simulations.

Why is it important?

Gallium oxide devices have great application prospects in the field of aerospace, but their degradation in space radiation will restrict their application. This article explores the reasons for the degradation of gallium oxide devices in the space radiation environment, which can help guide devices that are more resistant to radiation.


Writing this article was a great pleasure as I hope that it will not only help scholars in the semiconductor field and aerospace field to study the device degradation mechanism, but also attract all friends who are interested in space, pay attention to the huge impact of space radiation on spacecraft. We will work together from all fields to make continuous progress in human aerospace industry.
