Gallium Oxide Holds Promise For X-ray Detectors


North Carolina State University team says the material works fast and is able to withstand high levels of radiation

New research from North Carolina State University finds that radiation detectors making use of single-crystal Ga2O3 allow for monitoring X-ray radiation in near-real time.

"We found that the Ga2O3 radiation detector worked very fast, which could 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. "This is particularly exciting because recent research tells us that Ga2O3has excellent radiation hardness - meaning it will keep doing its job even when exposed to high amounts of radiation.

"In short, we think this material is faster than many existing materials used in X-ray detection - and able to withstand higher levels of radiation."

For this study, the researchers made a radiation detector that incorporated a single-crystal sample of Ga2O3 with electrodes attached on either side. The researchers applied different bias voltages across the Ga2O3 while exposing the material to X-ray radiation.

The researchers found that there was a linear increase in current passing out of the Ga2O3 relative to the level of X-ray exposure. In other words, the higher the level of X-ray radiation exposure, the higher the increase in current from the Ga2O3.

"This linear relationship, coupled with the fast response time and radiation hardness, make this a very exciting material for use in radiation detector technologies," Yang says. "These could be used in conjunction with medical imaging technologies, or in security applications like those found at airports."

AngelTech Online Summit - Tuesday 19th May

The health and well-being of AngelTech speakers, partners, employees and the overall community is our top priority. Due to the growing concern around the coronavirus (COVID-19), and in alignment with the best practices laid out by the CDC, WHO and other relevant entities, AngelTech decided to postpone the live Brussels event to 16th - 18th November 2020.

In the interim, we believe it is still important to connect the community and we want to do this via an online summit, taking place live on Tuesday May 19th at 12:00 GMT and content available for 12 months on demand. This will not replace the live event (we believe live face to face interaction, learning and networking can never be fully replaced by a virtual summit), it will supplement the event, add value for key players and bring the community together – digitally.

The event will involve 4 breakout sessions for CS International, PIC International, Sensors International and PIC Pilot Lines.

Key elements of the online summit:

  • Covering key topics of the industries
  • Live 3 hour online summit
  • 10 minute presentations – learn from experts in the industry
  • Recorded product demos
  • Live audience questions
  • Enhanced discussion and audience interaction
  • Video panel sessions
  • Sponsors digital booth (intro video, company content, lead generator, facilitate one on one video meetings with attendees)
  • Live private video meetings between two or more attendees
  • After the live event, monthly keynotes to drive traffic to the event 24/7, 365

Innovation is in AngelTech’s DNA and we are leveraging this strength to bring you an immersive and inspiring online event without the risk of travel during this uncertain period.
