Synchrotron experiment will help to improve gallium arsenide sensors
Radiophysicist Anastasia Lozinskaya has conducted an experiment on the Diamond Light Source synchrotron in the Rutherford Appleton Laboratory (RAL) in the UK. She irradiated a sensor based on gallium arsenide compensated by chromium (HR GaAs: Cr), created at TSU with a beam of synchrotron radiation. The data obtained will help to improve the quality of the sensors and make the final picture more uniform.
- Recently some defects were detected in the structure of gallium arsenide, which we compensate for chromium. These defects lead to a change in the counting speed of the sensors, and as a result, the picture becomes heterogeneous, that is, small “spots” are visible with more or less charge collected, - said Anastasia Lozinskaya, junior scientific researcher at the center for research and development Advanced Technologies in Microelectronics. - In early 2019, we applied to Diamond Light Source for an experiment to improve the quality of our sensors.
