Abstract The radiation detection properties of Schottky detectors made on epitaxial layers of 4H silicon carbide were evaluated. Exposure to 5.48 MeV alpha particles from a 241 Am source in vacuum led to robust signals from the detectors. The collection of the charge carriers was found to increase linearly with the square root of the applied reverse bias.
At GE Research, semiconductor engineers and physicists tackle the most challenging problems involved when developing commercial devices and systems by applying their expertise in semiconductor device physics, device process integration and device testing.
