A collaborative team led by researchers from the Hefei Institutes of Physical Science<\/a> of the Chinese Academy of Sciences has successfully developed advanced semiconductor-based radiation detectors, significantly improving their performance for use in extreme environments.<\/p>\n

The achievements have been published in a paper<\/a> in IEEE Electron Device Letters<\/i> and three<\/a> articles<\/a> published<\/a> in Nuclear Instruments and Methods in Physics Research A<\/i>.<\/p>\n

Radiation detectors act as the “eyes” for scientists, enabling the observation and study of nuclear radiation and microscopic particles. Traditional detectors, however, often struggle with low sensitivity and limited adaptability to extreme conditions, restricting their effectiveness in high-temperature and high-radiation environments.<\/p>\n

In contrast, semiconductor-based detectors made from wide-bandgap and ultra-wide-bandgap materials offer several advantages, including higher temperature resistance, better radiation tolerance, and easier integration, making them promising for advancing radiation detection technology<\/a>.<\/p>\n

The team concentrated on optimizing the design, fabrication processes, and testing methodologies of semiconductor-based radiation detectors to address the shortcomings of existing technologies.<\/p>\n

One of the team’s major achievements was the development of large-area detectors made from a combination of p-NiO and \u03b2-Ga\u2082O\u2083 materials. These materials are known for their low leakage current and enhanced sensitivity. When coupled with specialized neutron detection materials, the team developed a thermal neutron detector made from Ga\u2082O\u2083, achieving nearly 1% efficiency in neutron detection\u2014marking a significant milestone as the first successful experimental test of this technology.<\/p>\n
