Semiconductor detectors are devices that use semiconductor materials, like silicon or germanium, to detect and measure various types of radiation, including gamma rays, X-rays, and particles. They work by converting the energy from incoming radiation into electrical signals, which can then be analyzed to determine the type and intensity of the radiation. These detectors are widely used in fields such as medical imaging, nuclear physics, and environmental monitoring. Their advantages include high sensitivity, compact size, and the ability to operate at room temperature, making them suitable for a variety of applications in both research and industry.
