Study Marks Gallium Oxide’s Strength for Future Radiation Detectors

New research from North Carolina State University finds that radiation detectors making use of single-crystal gallium oxide allow for monitoring X-ray radiation in near-real-time.

Study Marks Gallium Oxide’s Strength for Future Radiation Detectors

“We discovered that the gallium oxide radiation detector labored very quickly, which might offer benefits to many applications such as medical imaging,” says Ge Yang, an assistant professor of nuclear engineering at NC State and corresponding author of a paper on the work.

“That is exciting as recent analysis tells us that gallium oxide has excellent radiation hardness—meaning it will keep doing its job even when uncovered to high amounts of radiation.

For this study, the researchers made a radiation detector that incorporated a single-crystal pattern of gallium oxide with electrodes attached on both sides. The researchers utilized different bias voltages across the gallium oxide while exposing the fabric to X-ray radiation.

The researchers discovered that there was a linear enhance in present passing out of the gallium oxide relative to the extent of X-ray publicity. In different phrases, the upper the extent of X-ray radiation publicity, the upper the increase in current from the gallium oxide.

“This linear relationship, coupled with the fast response time and radiation hardness, makes this a very thrilling material for use in radiation detector technologies,” Yang says. “These might be used in conjunction with medical imaging technologies, or in security applications like those discovered at airports.”
